Have go-test timeout before the GH step timeout to gather information

[stevendpclark]

Description

• If we encounter a deadlock/long running test it is better to have go test timeout. As we've noticed if we hit the GitHub step timeout, we lose all information about what was running at the time of the timeout making things harder to diagnose.
• Having the timeout through go test itself on a long running test it outputs what test was running along with a full panic output within the logs which is quite useful to diagnose

• Backport Labels: If this PR is in the ENT repo and needs to be backported, backport
  to N, N-1, and N-2, using the backport/ent/x.x.x+ent labels. If this PR is in the CE repo, you should only backport to N, using the backport/x.x.x label, not the enterprise labels.
  • If this fixes a critical security vulnerability or severity 1 bug, it will also need to be backported to the current LTS versions of Vault. To ensure this, use all available enterprise labels.
• ENT Breakage: If this PR either 1) removes a public function OR 2) changes the signature
  of a public function, even if that change is in a CE file, double check that
  applying the patch for this PR to the ENT repo and running tests doesn't
  break any tests. Sometimes ENT only tests rely on public functions in CE
  files.
• Jira: If this change has an associated Jira, it's referenced either
  in the PR description, commit message, or branch name.
• RFC: If this change has an associated RFC, please link it in the description.
