Hide all complete for group migration table
### Problem to solve
Once a user imports groups from their connected source instance they have 3 possible results of a single import, `Complete`, `Failed`, and `Canceled`. For enterprise businesses, the number of groups on the list could be 1000+ and sifting through them all is a daunting task.
How would a user be able to see only the failed groups so they could re-import the groups? How would they know how many groups completed from their source instance?
### User experience goal
By adding additional filter opportunities, the user has the ability to see the statuses of the groups in a more organized manner and narrow down the potentially overwhelming lists. The user is able to initiate a reimport on groups that have failed or have been canceled in a more efficient way.
### User stories
- When migrating groups, I need to see groups that have not yet been migrated so I can see which groups still need to be imported and understand which imports failed.
### Proposal

### Note
The patterns defined here could also be extended to all importers.
