Description of problem:

Opened a Ready ROSA Cluster installed in existing VPC (having custom security groups). Under machine pool tab, Once user opens the "Add machine pool" dialog , all the security groups loaded from the VPC. At the same time, if user create a security group in the VPC, then there is no option to refresh the security group from already opened dialog.User has to close and reopen the add machine pool dialog. To avoid this situation, we need option to refetch newly added SGs make it available in "Add machine pool" dialog.

Suggestions are

1. Introduce auto refresh in security group section with specified interval to fetch latest security groups. This could also trigger when user perform click action in "Security group" drop-down. OR
2. Introduce a refresh option (may be small icon) to fetch the latest SGs from backend.

How reproducible:

always

Steps to Reproduce:

1. Open OCM UI staging.
2. Open a Ready ROSA cluster  installed with custom VPC(VPC should have some Security groups associated).
3. Go to Machine pool tab.
4. Click "Add machine pool" button.
5. Create a security group in associated VPC.
6. Click "Security groups" drop-down.
7. See the list of security groups.

Actual results:

At step 6 , The latest security group added at step 5 wasn't listed. User has to reopen the dialog to fetch latest SGs.

Expected results:

Introduce options to refresh the SGs from the dialog without reopening existing definition
