So far, the datasource used to connect to the AccountPatchReviewStore
was using hard coded values for the pool connection settings. In high
traffic servers, those default values cause a bottleneck as the
transactions start to be queued when the max number of connections is
reached.
Add the possibility of specifying those values in the gerrit
configuration so they can be tailored to diverse needs.
