Add option to force molecule commands if the scenario is already created, prepared, or converged

[gciavarrini]

Sometimes it is required to run create, prepare, converge commands even if the scenario is already created, prepared, or converged.

It would be nice to add an option to force molecule actions like

> molecule prepare -f

I'm not sure why one want to create again a scenario even if it has already been created, so can't comment. For converge, I think it has been possible to run converge at will for ages (as long as the previous steps of the test matrix have succeeded).

For prepare, it's already possible to force-run it:

$ molecule --version
molecule 4.0.3 using python 3.9 
...
$ molecule prepare --help
Usage: molecule prepare [OPTIONS]

  Use the provisioner to prepare the instances into a particular starting state.

Options:
  -s, --scenario-name TEXT        Name of the scenario to target. (default)
  -d, --driver-name [delegated|docker|podman|vagrant]
                                  Name of driver to use. (delegated)
  -f, --force / --no-force        Enable or disable force mode. Default is disabled.
  --help                          Show this message and exit.

The ask is here to enable force option for all molecule commands.

When creating complex infrastructure it is nice to have force option to add some things, instead of creating all from scratch. Creating from scratch might not be possible for manually created and prepared hosts.
