features/shard: Make lru limit of inode list configurable
Currently this lru limit is hard-coded to 16384. This patch makes it
configurable to make it easier to hit the lru limit and enable testing
of different cases that arise when the limit is reached.
The option is features.shard-lru-limit. It is by design allowed to
be configured only in init() but not in reconfigure(). This is to avoid
all the complexity associated with eviction of least recently used shards
when the list is shrunk.
