Policy validation in Deckhand was not implemented completely. Refer link
below:
https://airshipit.readthedocs.io/projects/deckhand/en/latest/users/validation.html#policy-validations
This PS removes some of the code related to the feature which was being
used in a code path when a set of documents are uploaded to Deckhand.
In standard Airship deployments the number of documents could be quite
high and this leads to significant delay (more than 300seconds in some
cases). As there are no plans to implement the policy validation feature,
it makes sense to remove it from code path which could cause delay and
sometimes timeouts while uploading documents.
This has been tested on a Baremetal lab: GF and BF.
