Backport of Support restricted PSA enforcement part 2 into release/1.2.x

[pglass]

Manual backport of #2702 into release/1.2.x because the backport job failed to generate a PR.

The below text is copied from the body of the original PR.

Changes proposed in this PR:

Part 2 of #2572.

Update the following to set a "restricted" security context:

• create-federation-secret-job.yaml
• ingress-gateways-deployment.yaml
• mesh-gateway-deployment.yaml
  • This is not included because adding the "restricted" security context settings to MGW makes it impossible to use hostNetwork=true
• partition-init-job.yaml
• terminating-gateways-deployment.yaml
• sync-catalog-deployment.yaml

Also, fix a WAN federation test to run on kind

How I've tested this PR:

Run acceptance tests on kind with restricted PSA enforcement enabled on the consul namespace (see script)

• Run the WAN fed test that is fixed in this PR, in order to validate the create federation secret job and mesh gateway deployment
• Run TestTerminatingGateway and TestIngressGateway and manually validate the gateways start and run successfully in the restricted consul namespace
  • (note: these tests fail when test applications are deployed to a restricted namespace, because the test applications do not support running in a restricted namespace)
• Run TestPartitions_Gateway and manually validate the partitions-init job succeeds

Test script:

• Run make kind and then ./test-psa-kind.sh (no tproxy) or ./test-psa-kind.sh -tproxy (tproxy enabled). Toggle comments at the bottom to try to run other tests.
• Run make kind-cni and ./test-psa-kind.sh -cni to test with tproxy+cni
