feat: add backup path (#10649)
## Description
Closes:  #10533

Cosmovisor can cause problems related to disk space when they try backing up, not enough space might fail the node.
A new feature is added to allow user to set a backup path, which can be separated from the node-home directory.
A new env var `DAEMON_BACKUP_DIR` is added. If `DAEMON_BACKUP_DIR` is set, backups will go there instead of `DAEMON_HOME`. 

- [x] add custom data backup dir 
- [x] add tests

fix(cosmovisor): udpate the help and version command output (#10458)
## Description

Closes: #10450

* `cosmovisor help` should not print any error. 
* `cosmovisor version` should print more clear message if it can't run `app version`.

## Before 

```
~/tmp ❯ cosmovisor version
Cosmosvisor - A process manager for Cosmos SDK application binaries.

Cosmovisor is a wrapper for a Cosmos SDK based App (set using the required DAEMON_NAME env variable).
It starts the App by passing all provided arguments and monitors the DAEMON_HOME/data/upgrade-info.json
file to perform an update. The upgrade-info.json file is created by the App x/upgrade module
when the blockchain height reaches an approved upgrade proposal. The file includes data from
the proposal. Cosmovisor interprets that data to perform an update: switch a current binary
and restart the App.

Configuration of Cosmovisor is done through environment variables, which are
documented in: https://github.com/cosmos/cosmos-sdk/tree/master/cosmovisor/README.md

## Description

Closes: #10378

Cosmovisor module copies the data type `UpgradeInfo` and constant `upgradeFilename` from upgrade module to cosmovisor module.
This pr will directly import the datatype and const from cosmos-sdk/upgrade module:
`UpgradeInfo` ->  `upgradetypes.Plan`
`upgradeFilename` -> `upgradekeeper.UpgradeInfoFilename`

refactor: move from io/ioutil to io and os package (#10341)
## Description

The `io/ioutil` package has been deprecated in Go 1.16 (See https://golang.org/doc/go1.16#ioutil). Since cosmos-sdk has upgraded to Go 1.17 (#9987), this PR replaces the existing `io/ioutil` functions with their new definitions in `io` and `os` packages.

feat: Add cosmovisor --help (#10229)
* [10126]: Create the help text and a func for checking if help is requested.

* [10126]: Check if help is requested and print it if so.

* [10126]: If help is requested, and it's possible, also run the binary with the --help flag.

* [10126]: Add a Config method for creating a detailed string.

* [10126]: Include the config detail string if the config is okay.

* [10126]: Create a MultiError error.

* [10126]: Get all configuration errors rather than just one at a time.

* [10126]: Create unit tests on the MultiError.

* [10126]: Remove an extra space from an output string.

* [10126]: Add unit tests on more of the args stuff.

* [10126]: Export the environment variable name strings.

* [10126]: Move the help command stuff into the new cmd area.

* [10126]: Move the unit tests on the help stuff that just got moved.

* [10126]: Lint fixes.

* [10126]: Export the EnvPreupgradeMaxRetries const and handle its error the same way as the others.

* [10126]: Update the args test with the new config entry.

* [10126]: Add EnvPreupgradeMaxRetries to the help text.

* [10126]: Output the full path in the error when the root isn't a directory.

* [10126]: Add some newlines that were missing from some help output.

* [10126]: Add a link to the documentation to the help text.

* [10126]: Don't allow MultiErrors to be in MultiErrors by extracting sub-errors while flattening.

* [10126]: Add some missing function comments.

* [10126]: Add changelog entry.

* [10126]: Fix changelog pull link.

* [10126]: Move multierror into its own errors package, then rename it to just multi.

* [10126]: Change the Config DetailString to use the environment variables instead of Config field names. Also add the missing PreupgradeMaxRetries entry to it.

* [10126]: Remove the environment variables from the help text and just defer to the cosmovisor README.

* [10126]: Update the help text as suggested.

* [10126]: Update ShouldGiveHelp. Give help if either name or home env vars aren't set. Give help if the first arg is help or any args are -h or --help. This reflects cobra defaults.

* [10126]: Pass all args when running a help command rather than just using --help.

* [10126]: Undo the changes to process.go. Instead, if an app is configured, just call it with the provided args.

* [10126]: Output help if any arg is help.

* [10126]: Reorg imports.

* [10126]: Change 'Monitored Upgrade Info File' to just 'Monitored File'. The rest of the filename gives the rest of the context.

* [10126]: Move the config error handling and output out of DoHelp and put it into the main Run function. That way, it's not being done twice in two different ways, and the setup is always logged.

* [10126]: Make checking for a help request case-insensitive (to match what's done in version).

* [10126]: Fix unit test that broke when I changed the Monitored File title.

* [10126]: Change some unit test env var stuff to use a struct instead of string slices.

feat: file watcher for cosmovisor (#8590)
Adding upgrade file watcher for cosmovisor.

Currently the comswisor upgrade mechanism relays on parsing log messages. This is not reliable:
+ depends on the log level output (x/upgrade uses INFO)
+ can be hacked by accidentally logging user user content
+ can be broken by using upgrade name which will break the regex pattern.

## Description

Ref: https://github.com/cosmos/cosmos-sdk/issues/9616#issuecomment-873051972

depends: #8590

<!-- Add a description of the changes that this PR introduces and the files that
are the most critical to review. -->

This PR adds a full backup option for cosmovisor. 
`UNSAFE_SKIP_BACKUP` is an `env` setting introduced newly.
- if `false` (default, **recommended**), cosmovisor will try to take backup and then upgrade. In case of failure while taking backup, it will just halt the process there and won't try the upgrade.
- If `true`, the cosmovisor will try to upgrade without any backup. This setting makes it hard to recover from a failed upgrade. Node operators either need to sync from a healthy node or use a snapshot from others.

cosmovisor: various small improvements (#7275)
{,cosmosvisor/}Makefile: Add Makefile to cosmovisor/
subdirectory and integrate build target into the
top-directory Makefile.

cosmovisor/:

Create Golang-idiomatic cmd/ subdirectory to make
`cosmosvisor` binary (instead of a binary named `cmd`)
automatically installable with `go get`.

Minor changes to error handling:

- Plain error strings bring more value than the whole
  stacktrace in case of dumb configuration errors.

- Output errors to /dev/stderr instead of /dev/stdout.

Remove dependency on github.com/pkg/errors.
