CLOUDSTACK-9564: Fix memory leaks in VmwareContextPool
In a recent management server crash, it was found that the largest
contributor
to memory leak was in VmwareContextPool where a registry is held (arraylist)
that grows indefinitely. The list itself is not used anywhere or consumed.
There
exists a hashmap (pool) that returns a list of contexts for existing poolkey
(address/username) that is used instead.
This fixes the issue by removing the arraylist registry, and limiting the
length of the context list for a given poolkey.
