[STORM-636] Faster, optional retrieval of last component error
We want to speed up interactions with the topology that call
getTopologyInfo, including the Topology Page in the UI.
Before change:
- Errors written to /errors/topo-id/comp-name/eN, where N is a sequence
number.
- getTopologyInfo grabs all /errors/topo-id/*/* errors from ZK
After this change:
- Errors written to /errors/topo-id/comp-name/eN, where N is a sequence
number. (unchanged)
- Errors also written to /errors/topo-id/comp-name-last-error (this means
there is an extra ZK write per error)
- New Nimbus thrift interface method `getTopologyInfoWithOpts`
- Only option right now is how many errors to retrieve from ZK: 0, 1, or
all.
