DEPL-6622: Release jenkins plugin 4.5.0 that works with XLD 4.5.1

This is a series of commits that should work with XLD 4.5.1. Unfortunately, hidden properties are hardcoded to false in RemoteDescriptor so we need to wait for a new version of remote-booter that fixes this in order to resolve DEPL-4899 (do not show hidden properties in the UI).
It's a feature in SLF4J since v1.6.0:

In the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will now presume that the user wants the last argument to be treated as an exception and not a simple parameter. See the relevant FAQ entry for further details. This fixes bug 70 submitted by Joern Huxhorn who also provided the relevant patch.
