Add option only_status (#210)

Developers sometimes leave the workflows in queued state. This happens
when you have a protected environment and deployment is waiting for
approval. They sometimes do not approve and just leave the workflow
pending waiting for a merge that will start a new workflow run and
deploy from there multiple merges at once.

We need to cancel the older pending ones if new PR is merged but SKIP
canceling workflows that are running as it might be dangerous to
interrupt it. To play it safe we introduce `only_status: 'waiting'` in
order to avoid canceling runs with status `in_progress`

GitHub official implementation also does not support this option and
they do not have plans to implement it soon, so we are adding it to this
action

+### Advanced: Skip runs that are in progress
+
+Some workflows may be dangerous to cancel when they are in progress. If you want to play safe and cancel only workflows that are in state `waiting`, most likely waiting for approval to be deployed in a protected environment, use `only_status` to only cancel runs with a specific status. 
+
+```yml
+name: Cancel
+on: [push]
+jobs:
+  cancel:
+    name: 'Cancel Previous Runs'
+    runs-on: ubuntu-latest
+    timeout-minutes: 3
