The previous version of menu_launch_type took the name of the
application as an argument and it started the application.
To maximize the application or to check that it has started indeed
we had to do it manually.
Now, the application also takes "maximize => 1" or "checkstart => 1"
to maximize the application or check that it has started as optional
arguments to avoid doing it manually, while it still accepts just
the name of the application and behaves like it did before.
Note that if you decide to use the checkstart argument, you
also need to update the check-needles.py script to whitelist
the application needle tag, see the example test scripts
attached to this PR.
Fixes: https://pagure.io/fedora-qa/os-autoinst-distri-fedora/issue/329
This PR tries to respond to issue #294.
On Silverblue, this will try:
* flatpak install
* flatpak remote-add
* flatpak list
* flatpak remotes
* flatpak remove
* flatpak update
and also it tests that a flatpak can be built.
