`RedisLockRegistry` missing crucial logging messages

[Haarolean]

In what version(s) of Spring Integration are you seeing this issue?

6.1.1

Describe the bug

Currently, RedisLockRegistry logs the moment a lock is release:

if (LOGGER.isDebugEnabled()) {
    LOGGER.debug("Released lock; " + this);
}

But there's no such a thing logged for the event of acquiring such a lock. The only way around this would be probably enabling redis queries logging which is not ideal.
I believe understanding both the moments a lock is acquired and release is important for debugging problems, but spring integration doesn't provide such a possibility.
I'd be happy to raise a PR if we find this useful.

Expected behavior

Logging the event of acquiring a lock.

Sure thing! Feel free to open pull request and we’ll look next week.
Thank you!

I have scheduled this for the next 6.2.1 and I don't treat this as a bug.
If you issue the PR, then we can consider to back-port it.

Thanks
