Title: CAS-1140 Additional monitors for vital CAS components.

New monitors:
- ContextSourceMonitor (monitors LdapContextSource)
- DataSourceMonitor (generic data source/pooled data source monitor)
- EhCacheMonitor
- MemcachedMonitor

Minor refactoring of existing monitors to conform convention of required versus optional parameters.
