add test for reconfigure, release, suspend, abort and disconnect.
app_config_req and app_reconfig_req always accept the req,
so don't need to handle reject case.

The API directory really isn't the best place for shell
documentation, which isn't API.
Created a new directory for Bluetooth shell documentation
and moved the ISO and LE Audio docs in there.
The existing bluetooth-shell.rst file was also split into
several new files, so that it follows the same structure.
