Description

To allow for fast persistence of profiles on a temporary basis (i.e. till the life of the Drillbit), an existing test class org.apache.drill.exec.testing.store.NoWriteLocalStore.java was refactored to org.apache.drill.exec.store.sys.store.EphemeralPersistentStore and given the ability to maintain a max capacity.

This should allow query profiles to be available for as long as the Drillbit process' lifespan.
