Have Heimdall report profile status and status_message

[wdower]

Heimdall should report the status and status_message of loaded HDF in the summary info so that users can tell if there's been an issue like an invalid target. At present, loading HDF that resulted from running a profile against an unsupported platform (ex. running the RHEL7 STIG profile against RHEL8) will produce a JSON that will successfully load in Heimdall but will not indicate that the reason there are no controls is because the target was not supported.

We should:

1. display the status and status_message for each profile in the profile summary window
2. If the status of a profile is skipped, have Heimdall display a profile error
