Harden verification OpenStack CLI calls to use JSON output

[tusharjadhav3302]

Summary

• Replace fragile openstack … -f value / -c / csv+grep usage in verification with -f json and structured Ansible (or jq) parsing.
• Fixes the 4.23-class failure on floating ip show … -c fixed_ip_address -f value → Invalid formatter provided in check_lb_svc.yml.
• Covers Priority A verification path only: LB FIP checks, cinder CSI AZ lookup, Swift registry object scan, prometheus PVC volume check, and manila catalog presence.

Test plan

• ansible-lint / dry-read touched YAML
• Confirm OSC -f json keys locally if possible (fixed_ip_address, vip_address, provider, availability_zone)
• Watch next shiftstack-rhel9-rhoso18.0-ocp423 (and other version nightlies): LB FIP task must not fail with Invalid formatter provided; cinder/registry/prometheus/manila checks still pass when enabled

Manual validation on shiftstackclient (serval71 / MR !2584 env)

openstack floating ip show <ip> -f {json,yaml,shell,table,value} all fail with Invalid formatter provided (despite help listing those formatters).

Working approach:

openstack floating ip list --floating-ip-address <fip> -f json
# keys: "Floating IP Address", "Fixed IP Address", "ID", ...

openstack loadbalancer list -f json works (keys: vip_address, provider, …).

Pushed a follow-up commit switching FIP lookup/removal checks to floating ip list.

Validation update (via throwaway #34)

OSC JSON / FIP verification path was exercised in testproject !2584 when pinned to combine PR #34 (refs/pull/34/head):

• Job fetched the combine (includes this PR)
• Install + verification (incl. check_lb_svc) completed — no real Invalid formatter provided on floating ip show … -f value
• day2ops SUCCESS
• Job then failed later in openstack_test for an unrelated OTE reporting issue (addressed in Adapt openstack_test stage to OTE (drop legacy make openstack-tests) #33), not in verification

Follow-up manual work on serval71 focused on #33/openstack_test; this PR’s verification fix remains in good shape for merge once reviewers are happy. TP recheck with refreshed #34 is still pending for an end-to-end green/unstable path.

Manual validation complete (serval71) — still targeting Zuul green

Full post-install path exercised on a live RHOSO + guest OCP 4.23 cluster using throwaway combine #34 (includes this PR).

Stage	Result
verification (this PR — OSC JSON / FIP)	Pass (earlier TP !2584 with #34; no Invalid formatter on LB FIP)
day2ops	Pass (same TP)
openstack_test / lb_tests / egressip	See #33 — automation OK; not blocked by this PR

We will still drive Zuul green on testproject !2584 (pin refs/pull/34/head) for an official check run before merge.
