LGTM.

But to do left:

1. The mentioned minor changes
2. The docs improvements reminder
3. I'm not sure (I don't want to go through the PR again) - did you fix some Windows-related issues in this PR too? If so, it'd be nice to mention them in the changelog description.

1. IMPORTANT: I reverted adding synchronized on getPort method. It turned out, that this method is called during container startup, for example during RorStartingSuite tests. I think synchronized is not strictly required in that method (it it a read-only operation in a given moment in time)

2. oneliner PR in docs [RORDEV-1472] Added notice about regex format on Windows beshu-tech/readonlyrest-docs#282

3. there is only one thing - fixed double-encoding of LDAP cn (I caused LDAP tests to fail on Windows. I am not sure if it would cause production issues, perhaps it depends on LDAP used. Added to changelog)
