Moved creation of GerritPersonIdent to a separate provider.

It's first step to make GerritServer focused on providing one specific
functionality.

Since now classes that need PersonIdent that represents Gerrit itself can
ask for it using @GerritPersonIdent annotation or by depending on Provider
instance and calling get() method.
