Accountsdb replication installment 2 (#19325)
This is the 2nd installment for the AccountsDb replication.

Summary of Changes

The basic google protocol buffer protocol for replicating updated slots and accounts. tonic/tokio is used for transporting the messages.

The basic framework of the client and server for replicating slots and accounts -- the persisting of accounts in the replica-side will be done at the next PR -- right now -- the accounts are streamed to the replica-node and dumped. Replication for information about Bank is also not done in this PR -- to be addressed in the next PR to limit the change size.

Functionality used by both the client and server side are encapsulated in the replica-lib crate.

There is no impact to the existing validator by default.

Tests:

Observe the confirmed slots replicated to the replica-node.
Observe the accounts for the confirmed slot are received at the replica-node side.

Make background services aware of incremental snapshots (#19401)
AccountsBackgroundService now knows about incremental snapshots.  It is
now also in charge of deciding if an AccountsPackage is destined to be a
SnapshotPackage or not (or just used by AccountsHashVerifier).

!!! New behavior changes !!!

Taking snapshots (both bank and archive) **MUST** succeed.

This is required because of how the last full snapshot slot is
calculated, which is used by AccountsBackgroundService when calling
`clean_accounts()`.

File system calls are now unwrapped and will result in a crash. As Trent told me:

>Well I think if a snapshot fails due to some IO error, it's very likely that the operator is going to have to intervene before it works.  We should exit error in this case, otherwise the validator might happily spin for several more hours, never successfully writing a complete snapshot, before something else brings it down.  This would leave the validator's last local snapshot many more slots behind than it would be had we exited outright and potentially force the operator to abandon ledger continuity in favor of a quick catchup

Other errors will set the `exit` flag to `true`, and the node will gracefully shutdown.

Name snapshots consistently (#19346)
#### Problem

Snapshot names are overloaded, and there are multiple terms that mean the same thing. This is confusing. Here's a list of ones in the codebase that I've found:

```
- snapshot_dir
- snapshots_dir
- snapshot_path
- snapshot_output_dir
- snapshot_package_output_path
- snapshot_archives_dir
```

#### Summary of Changes

For all the ones that are about the directory where snapshot archives are stored, ensure they are `snapshot_archives_dir`. For the ones about the (bank) snapshots directory, set to `bank_snapshots_dir`.

Add snapshot_utils::bank_from_latest_snapshot_archives() (#18983)
While reviewing PR #18565, as issue was brought up to refactor some code
around verifying the bank after rebuilding from snapshots.  A new
top-level function has been added to get the latest snapshot archives
and load the bank then verify.  Additionally, new tests have been
written and existing tests have been updated to use this new function.

Fixes #18973

While resolving the issue, it became clear there was some additional
low-hanging fruit this change enabled.  Specifically, the functions
`bank_to_xxx_snapshot_archive()` now return their respective
`SnapshotArchiveInfo`.  And on the flip side,
`bank_from_snapshot_archives()` now takes `SnapshotArchiveInfo`s instead
of separate paths and archive formats.  This bundling simplifies bank
rebuilding.

Do not shell out for tar (#19043)
When making a snapshot archive, we used to shell out and call `tar -S`
for sparse file support.  The tar crate supports sparse files, so no
need to do this anymore.

Fix wrong old snapshot archives getting purged (#19061)
I introduced a bug where old snapshot archives were incorrectly purged.
Instead of purged to oldest, I was purged the newest...

The fix is to add a `reverse()` in the purge logic, and I've added a
test to catch this bug in the future.
