[infinispan-dev] Remove cache issues

[Pedro Ruivo]

Hi,

I found the following issues with _EmbeddedCacheManager.removeCache()_ 
while I was helping the LEADS devs. The method removes the cache from 
all the nodes in the cluster.

#1 It has different behaviour in the invoker node.

In the invoked node, it removes the configuration from 
_configurationOverrides_ field and from _cacheDependencyGraph_. In the 
remaining node, it doesn't.

To think: it should remove from _cacheDependencyGraph_ in all the nodes 
but keep the configuration.

#2 It tries to remove the cache remotely before locally.

It could be done in parallel and it has a small issue: if a timeout 
occurs, it never tries to remove the cache locally.

To think: can we send the request asynchronously?

#3 When passivation is enabled, it first invoke 
_PassivationManager.passivateAll()_ and then _PersistenceManager.stop()_.

The former will copy all the data in memory to the cache store and the 
later will clear the cache store. We can skip the passivation.

To think: create a _PassivationManager.skipPassivationOnStop()_ (similar 
to _PersistenceManager.setClearOnStop()_).

Comments are welcome.

Cheers,
Pedro
