[PATCH rt-tests v1 07/23] rt-migrate-test: Rename command line option --output to --json

[Daniel Wagner <dwagner@suse.de>]

The initial idea was to have several different output format
supported but it turns out everyone is happy with JSON, so
there is no need to add another format.

Thus let's make the command line option more specific and
rename it to --json.
