This change allows users that build their own executable or "spin" of
OPA to give it a name, and have it reference itself properly in help
texts.
It's a vanity thing, but I think some people would appreciate it, hat
tip to the international association of pedants.

`os.Exit` immediately exits the program and doesn't run defer functions.
This can be problematic as any command.OnFinalize routines and any logic
after the command.Execute won't be run.
Also suppress all RunE cobra error and usage messages. These would be
printed twice otherwise.

There is a new command argument "capabilities". With this, it is
possible to print the current capabilities version, show all
capabilities versions & print any capabilities version, without the need
of a file. Moreover, for the other commands which use the --capabilities
flag, it is possible to give only the version number, without specifying
a file. However, there are no breaking changes for those who use the
capabilities file as an input for the flag. Unit tests were also
written, in order to test the new argument and the changes made in ast.
Fixes: #4236
