This fixes two bugs:

  • admission mutators are invoked before validation, so we must handle invalid input in mutation
  • fix validation error aggregation so we always return nil

Sample failure is https://circleci.com/gh/hashicorp/nomad/15559 . The test covers both of these cases, but the panic in one caused test runner to skip running the other failing test case :(.

Fixes #6571

`groupConnectHook` assumes that Networks is a non-empty slice, but TG
hasn't been validated yet and validation may depend on mutation results.
As such, we do basic check here before dereferencing network slice
elements.
`admissionValidators` doesn't aggregate errors correctly, as it
aggregates errors in `errs` reference yet it always returns the nil
`err`.

Here, we avoid shadowing `err`, and move variable declarations to where
they are used.
