Create solo Github Action for reusability and rapid adoption

[leninmehedy]

Requested Feature

We need a publicly available Github Action (solo-gh-action) that can be used by everyone else to provision a solo network and run tests in their CI pipeline.

Business Need

Hedera community developers need the ability to quickly setup a solo network in their Github Action to run tests. Currently devs needs to duplicate the effort of setting up a solo network in their Github action. It would be far more efficient if the solo dev team could publish a Github Action (maybe later to Github Marketplace?) that everyone else can use.

It also provides more control about the updates with urgent fixes so that community don't need to spend too much time to use the latest solo version in their pipeline.

Additional Context

We already have code to setup solo network in Github Action, so it shouldn't take long. We just need to extract it in a new repo solo-gh-action, polish it up and publish.

NOTE: @nathanklick helped @hendrikebbers create this: https://github.com/OpenElements/hedera-solo-action

We might be better to just enhance that project instead of creating another action.
