Events/msgtype cleanup (#9117)
* 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

Michael Schurter 4c5a0cae35 core: fix node reservation scoring
The BinPackIter accounted for node reservations twice when scoring nodes
which could bias scores toward nodes with reservations.

Pseudo-code for previous algorithm:
```
	proposed  = reservedResources + sum(allocsResources)
	available = nodeResources - reservedResources
	score     = 1 - (proposed / available)
```

The node's reserved resources are added to the total resources used by
allocations, and then the node's reserved resources are later
substracted from the node's overall resources.

The new algorithm is:
```
	proposed  = sum(allocResources)
	available = nodeResources - reservedResources
	score     = 1 - (proposed / available)
```

The node's reserved resources are no longer added to the total resources
used by allocations.

My guess as to how this bug happened is that the resource utilization
variable (`util`) is calculated and returned by the `AllocsFit` function
which needs to take reserved resources into account as a basic
feasibility check.

To avoid re-calculating alloc resource usage (because there may be a
large number of allocs), we reused `util` in the `ScoreFit` function.
`ScoreFit` properly accounts for reserved resources by subtracting them
from the node's overall resources. However since `util` _also_ took
reserved resources into account the score would be incorrect.

Prior to the fix the added test output:
```
Node: reserved     Score: 1.0000
Node: reserved2    Score: 1.0000
Node: no-reserved  Score: 0.9741
```

The scores being 1.0 for *both* nodes with reserved resources is a good
hint something is wrong as they should receive different scores. Upon
further inspection the double accounting of reserved resources caused
their scores to be >1.0 and clamped.

After the fix the added test outputs:
```
Node: no-reserved  Score: 0.9741
Node: reserved     Score: 0.9480
Node: reserved2    Score: 0.8717
```

Fixes device scheduling unit tests
Also changes the logic for score when there is more than one task
requesting a device. Since inter task affinities are already normalized,
we take the average of the scores across tasks.
