fix(ESSNTL-3730): Refresh groups when new created

[gkarat]

Addresses https://issues.redhat.com/browse/ESSNTL-3730?focusedId=22178599&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-22178599.

Make it possible for the modal ("add host to group") to refresh the list of available groups after users have created the new one.

How to test

1. Run npm run start:proxy:beta
2. Navigate to https://stage.foo.redhat.com:1337/preview/insights/inventory
3. Find any available host and try to open "Add to group" modal
4. Try to create a new group, submit, then check that you are 1) redirected back to the main modal, 2) the list of available groups contains the group you have just created.
5. Try to select the new group and submit the modal.
6. You must get an error (405 error code) - this is expected, but the request should contain the id of the new group and also the id of the selected host.
