Assert tkts option defaults should include everything unless specified otherwise

[jwflory]

Summary

When a user imports tickets from Pagure to GitLab, the tool should default to including everything unless specified otherwise.

Background

When a user is running the tool, they are likely wanting to make a full copy of what is in Pagure to the extent as much is possible. Different metadata matters to different people. Things like labels and the current status of tickets could be very important data points for a team. Of course, not everyone reads the documentation and they might not realize what all options are available.

I predict it would result in a better user experience if the tool defaults to importing everything, to avoid a user having a negative user experience of realizing that data they thought would come with them did not.

Details

This is a "good first issue" that a new contributor could help with.

We need to change the default options in main.py so that the flags are enabled by default. Perhaps the names and help messages of the flags themselves could be made more clear as well about being omissions instead of additions when invoked.

Outcome

Better user experience when using the tool by porting out all relevant metadata and all issues (FULL) by default.

I'd be happy to work on this one too. So you can assign it to me.
