## 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`

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.

<!-- Add a description of the changes that this PR introduces and the files that

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.
