Wrap goodhosts under our own administrator CLI tool

[guillaumerose]

Currently, we compile and package goodhosts in CRC. It is slightly modified (go modules, version).
It is run as admin but it's not the only piece of code that we run as admin. We also have some shell and powershell commands that we run as admin.

The proposal is to create a new CLI tool in the code-ready organisation called admin-helper and just add the commands we need:

• Current goodhosts features (scoped to only crc.testing domain and not more for security)
• Add hosts file cleanup (we don't remove hosts we added in crc cleanup right now)

It will force us to maintain the admin binary more than what we currently do (we never upgraded goodhosts?).

In the "future", we could:

• Run this tool as an admin daemon for Windows.
• Use it for the vsock PoC to bind privileged ports.

Any thoughts?

Not a huge fan of hardcoding .crc.testing in many places when at the moment the crc code is mostly 'domain-independent'.
I'd add as a goal to minimize the amount of go packages which are used (apart from go standard library).

A good way to start could be to reuse https://github.com/code-ready/goodhosts-cli and diverge from here.

releases are already in place, etc. Maybe the CI is missing.

should be provided by the metadata. so either this tool needs to have an interface to deal with this on request, or know what to use from configuration (bundle provided) as people do us SNC to create them
