Replace gerrit.disableReverseDnsLookup with gerrit.enableReverseDnsLookup

Having a configuration option 'disable' with default value 'false'
results in a double-negative meaning which can be confusing.

Replace this option with enableReverseDnsLookup, with default 'true',
which effectively results in the same default behavior when no value
is configured.

Rename the DisableReverseDnsLookup and DisableReverseDnsLookupProvider
classes accordingly.
