Move version out of SDK. For now it's a copy rather than move: the part not addressed by this change is sdk/helper/useragent.String, which we'll want to remove in favour of PluginString. That will have to wait until we've removed uses of useragent.String from all builtins.
Check if plugin version matches running version
When registering a plugin, we check if the request version matches the
self-reported version from the plugin. If these do not match, we log a
warning.
This uncovered a few missing pieces for getting the database version
code fully working.
We added an environment variable that helps us unit test the running
version behavior as well, but only for approle, postgresql, and consul
plugins.
Return 400 on plugin not found or version mismatch
Populate the running SHA256 of plugins in the mount and auth tables (#17217)
Add plugin version to GRPC interface
Added a version interface in the sdk/logical so that it can be shared between all plugin types, and then wired it up to RunningVersion in the mounts, auth list, and database systems.
I've tested that this works with auth, database, and secrets plugin types, with the following logic to populate RunningVersion:
If a plugin has a PluginVersion() method implemented, then that is used
If not, and the plugin is built into the Vault binary, then the go.mod version is used
Otherwise, the it will be the empty string.
My apologies for the length of this PR.
* Placeholder backend should be external
We use a placeholder backend (previously a framework.Backend) before a
GRPC plugin is lazy-loaded. This makes us later think the plugin is a
builtin plugin.
So we added a `placeholderBackend` type that overrides the
`IsExternal()` method so that later we know that the plugin is external,
and don't give it a default builtin version.

strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

* Add extra debugging to help identify failures within mssql test
* Switch up the AssertInitialized method for mssql tests by marking the test as failed instead of
immediately failing, this will also allow us to see what happens even if this assertion fails to the rest
of the test.
* build out zombie lease system
* add typo for CI
* undo test CI commit
* time equality test isn't working on CI, so let's see what this does...
* add unrecoverable proto error, make proto, go mod vendor
* zombify leases if unrecoverable error, tests
* test fix: somehow pointer in pointer rx is null after pointer rx called
* tweaks based on roy feedback
* improve zombie errors
* update which errors are unrecoverable
* combine zombie logic
* keep subset of zombie lease in memory
This also temporarily disables couchbase, elasticsearch, and
mongodbatlas because the `Serve` function needs to change signatures
and those plugins are vendored in from external repos, causing problems
when building.
This is part 1 of 4 for renaming the `newdbplugin` package. This copies the existing package to the new location but keeps the current one in place so we can migrate the existing references over more easily.
* Add new Database v5 interface with gRPC client & server
This is primarily for making password policies available to the DB engine, however since there are a number of other problems with the current interface this is getting an overhaul to a more gRPC request/response approach for easier future compatibility.
This is the first in a series of PRs to add support for password policies in the combined database engine
