- improved handling for multiple IP addresses and IPv6

- removed assumptions of local vs. global network drivers

- server_cluster_httpget_from_peers not used anymore

Provide a default timeout of 5m to all ns_cache besed caches created via the acs-cache infrastructure

Background: in case, a db entry is to be cached, where the db query

does not finish (e.g. runs into a deadlock), subsequent attempts for

the same value will be blocked as well by the mutex protecting the

entry to be cached. Therefore, later requests to this entry might queue

up in the server. By providing a timeout, this mutex will terminate

latest when the timeout is reached.

The default value for the timeout is set to 5m. In case a certain

cache might issue requests running longer than this, the cache has

to be configured with a larger timeout value.

Prefer 'namespace which' over 'info commands', as it is faster (on local tests, around 2x) and returns a single value. Many thanks to Nathan Coulter.

Added HashKeyPartitionedCache:

This is type of cache is like a "KeyPartitionedCache" but works as

well with strings as keys while the "KeyPartitionedCache" requires numeric

keys.
