PROBLEM STATEMENT:
It's normal for folks to build clusters in an air-gap'd environment. In these environments access to the wider internet is strictly forbidden. We've known that there are several tests in the test suite require internet connectivity e.g. xref: #51287 , and this poses a problem for folks wanting to validate their cluster.

PROPOSED SOLUTION:

1. Create a predefined [Tag/Label] that can easily skip these tests for this type of environment
2. Create a framework function that detects and auto-skips tests that are known to require internet connectivity
