requirements-check: Umbrella for next phase

[johnSchnake]

• [ ] Review 3 projects for checks required #82, #83, #84, #93
• [ ] Document gaps in functionality and overlap from above
• [ ] Prioritize the above and make tickets for each feature

Current similarities outstanding:

• [ ] need to AND/OR checks to produce flow control. May be best to let this be a use case for vendoring the library rather than using the plugin directly.

New functionality needed:

• [ ] check if connected to internet
• [ ] check connectivity to OCI image registry (default dockerhub?)
• [ ] investigate and/or logic and how that could be implemented in a plugin; this is generally at odds with have a simple schema config that you just fill out though. It would involve having to hand-write more complex checks which are formed from combining other checks.
• [ ] Try POC for using this as a library to run and/or checks.

Questions to investigate:

• [ ] There was the idea that there were many more checks than this necessary as part of pre/post install. I need to re-review those pages and make sure I wasn't just looking at prereqs but also checks conducted during/after installation to ensure things were installed correctly.
