Description of problem:
After every back-and-forth navigation from VPC settings step from OSD wizard resulted a reloading of the VPC field. This is bad usability experience and we should avoid it.
There is backend request  "api/clusters_mgmt/v1/aws_inquiries/vpcs?fetchSecurityGroups=true"  calls every time in above case.
 
See recording attached  BackandForthVPCIssue.mp4
How reproducible:

always

Steps to Reproduce:

1. Open OCM UI staging.
2. Open OSD wizard (choose a CCS with cloud provider AWS)
3. Go Networking step and enable the " Install into an existing VPC option"
4. Click "Next" button.
5. Select a VPC  from the drop-down.
6. Click "Next" button.
7. Click "Back" button and see the VPC Settings page.
8. Click "Back" button.
9. Click "Next" button and see the VPC Settings page.

Actual results:

At step 7& 9 ,The VPC definition is refreshed and reloaded. This create wrong usability experience as VPC definition already fetch from backend.

Expected results:

At step 7& 9 ,The VPC definition should not be loaded every back-and-forth navigation. There should be any request to backend every time during the page navigation.
