[ST] Add NetworkPolicies for OpenTelemetryST when running on OCP

[im-konge]

Type of change

• Bugfix

Description

This PR fixes not working OpenTelemetryST on OCP, where we are enabling "default to deny" NetworkPolicies for all testcases.
It adds new generic NetworkPolicy related methods to NetworkPolicyResource, which can be useful also for different testcases and uses it in the Oauth as well.

Checklist

• Make sure all tests pass

Looks like generally good approach.
