Added a util directory for locator. 
PCLoadable is an interface for both PFS and DSS.
PCTimerTask covers both the extension of TimerTask and removes duplicate code.

> PropertyFileSnitch allows reloading changes from its config file manually.  
> DatacenterShardStrategy doesn't allow reloading at all [after I ripped out 
> the reload-for-each-getNaturalEndpoints call code, in CASSANDRA-1103].
> Let's check each of these for changes (modification time on the fs is 
> sufficient) every minute and reload automatically if changes are seen.  The 
> manual-reload code from PFS can then be dropped.
