[Feat]: Configuration Attestor

[jkjell]

Describe the solution you'd like:

A pre-material attestor could capture the configuration of the witness run operation to ensure the command was observed with the proper set of configuration values.

User value:

This will allow an additional layer of protections to subsequent policy verification to ensure the intent of process observation matches reality.

Expected behavior:

A configuration attestor captures relevant CLI parameters and stores them in the attestation-collection

Testing changes required:

Unit tests of the new attestor and policy test to ensure functionality

Documentation changes required:

Document json schema and context of the new attestor.
