* use msgtype in upsert node
adds message type to signature for upsert node, update tests, remove placeholder method
* UpsertAllocs msg type test setup
* use upsertallocs with msg type in signature
update test usage of delete node
delete placeholder msgtype method
* add msgtype to upsert evals signature, update test call sites with test setup msg type
handle snapshot upsert eval outside of FSM and ignore eval event
remove placeholder upsertevalsmsgtype
handle job plan rpc and prevent event creation for plan
msgtype cleanup upsertnodeevents
updatenodedrain msgtype
msg type 0 is a node registration event, so set the default to the ignore type
* fix named import
* fix signature ordering on upsertnode to match
* state_store: csi volumes/plugins store the index in the txn
* nomad: csi_endpoint_test require index checks need uint64()
* nomad: other tests using int 0 not uint64(0)
* structs: pass index into New, but not other struct methods
* state_store: csi plugin indexes, use new struct interface
* nomad: csi_endpoint_test check index/query meta (on explicit 0)
* structs: NewCSIVolume takes an index arg now
* scheduler/test: NewCSIVolume takes an index arg now
This brings test code and mocks up to date with the fingerprinter. This was a slightly larger change than I anticipated, but I think it's good for two reasons:
1. More semanitcally correct. `os.name` is something like "Windows 10 Pro" or "Ubuntu", while `kernel.name` is "windows" or "linux". `os.version` and `kernel.version` match these semantics.
2. `kernel.name` is much easier to grep for than `os`, which is helpful because oracle can't help us with strings.
