Lps 49445 Prepare PortalCacheManager to be managed by PortalCacheProvider.

Hi Shuyang,

To be managed by PortalCacheProvider, each PortalCacheManager:
1) has a unique name
2) needs to know if it is clusterable, this property is to determine if a PortalCacheManager can do cluster operations like bootstrap and replication.

There is an abstract cache manager named BaseIntrabandPortalCacheManager, I am not sure how it is used and if I need to do something to make sure the two rules above.

Any question, please let me know.

Thanks.
Tina.
