manager: Add options to change self test behaviour

Added new `kata-manager` options to control the self-test behaviour. By
default, after installation the manager will run a test to ensure a Kata
Containers container can be created. New options allow:

- The self test to be disabled.
- Only the self test to be run (no installation).

These features allow changes to be made to the installed system before
the self test is run.

Fixes: #3851.
