### What changes were proposed in this pull request?
When registering a resource profile, check if one with the same requests
already exists. If so, return it, so that the same executors can be reused.
### Why are the changes needed?
Currently, every time a profile is registered, new executors will need to
spin up -- even if the resource requests are the same. This is especially
problematic with Spark Connect, where different isolated sessions may try and
register the same profile, but all end up with isolated executors.
### Does this PR introduce _any_ user-facing change?
<!--
Note that it means *any* user-facing change including all aspects such as
new features, bug fixes, or other behavior changes. Documentation-only updates
are not considered user-facing changes.
If yes, please clarify the previous behavior and the change this PR proposes
- provide the console output, description and/or an example to show the
behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to
the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.
