In #3520, work was done to true up the defaults for Nomad resource
stanzas with the documentation. This fixes the tests that I
accidentally broke in the process. Some questions were raised about
using dynamic elements as part of expects, which is why I opted to
copy the MinResources pattern. During this refactor I also noticed
that structs.go had a similar issue and an inconsistent minium for CPU.
This commit:
* Fixes the error checking in migration tests now that we are using the
canonical ErrPermissionDenied error
* Guard against NPE when looking up objects to generate the migration
token
* Handle an additional case in ShouldMigrate()
This PR fixes:
* An issue in which a node-drain that contains a complete batch alloc
would cause a replacement
* An issue in which allocations with the same name during a scale
down/stop event wouldn't be properly stopped.
* An issue in which batch allocations from previous job versions may not
have been stopped properly.
