Updates net-ldap
gem: https://github.com/ruby-ldap/ruby-net-ldap to 0.16.3
It eliminates some Ruby 2.7 kwargs warnings and provides multiple useful improvements

Diff: https://github.com/ruby-ldap/ruby-net-ldap/compare/v0.16.2..v0.16.3
There's 0.17.0
version already available, but it removes ConnectionRefusedError
which exists in our code. Since 0.16.3
still removes the 2.7 warning, let's go the safer way
