feat(groups): improve consumer groups loading

[AlexisSouquiere]

• Fix Unable to display the consumer groups of a topic  #1863

Add a dropdown list on the topic screen/consumer groups tab to allow people selecting "Hide empty consumer groups".
This option fixes issues on this screen with cluster containing a lot of consumer groups because we were looping over all the consumer groups and requesting the cluster for their offsets to find the right topics.

Ignoring empty consumer groups allows AKHQ to give the response quickly because we will search for the topic directly in the member assignation instead of having also the check in the groups offsets (for empty consumer groups)

• Add the possibility to choose the default value (like the topic list view) in the application.yml (general settings or by cluster) and in the settings screen

• Fix consumer group loading in topic list table
  Same issue as the previous one, with a lot of consumer groups, the consumer groups column in the topic list table takes a lot of time to show the result (when you don't reach a timeout).

By reusing the new "Consumer Groups Default View", AKHQ will now be able to show the active consumer groups quickly

On a cluster with 1500+ consumer groups, it allows us to finally see (at least) the active groups in few seconds
