Reduce CRD size by removing some descriptions for things that:

1. are long
2. are repeated
3. common kubernetes types.

Remove the Status field from VolumeClaimTemplates (a.k.a. PVCs) in types.go to remove all unnecessary status-related fields.

Use yq to go through generated crds.yaml to strip out descriptions for well-known k8s types that are long and repeated where we can't remove them from types.go. This is mostly placement descriptions and volumeSource descriptions.

The overall crds.yaml file is reduced to less than 60% of its original size.

Manual upgrade testing:

New image is upgraded correctly, and cluster is healthy after the upgrade:

bash-4.4$ ceph -s
  cluster:
    id:     554d990f-2e29-4935-ad5a-31403c10d18b
    health: HEALTH_OK
 
  services:
    mon: 1 daemons, quorum a (age 31m)
    mgr: a(active, since 30s)
    osd: 3 osds: 3 up (since 28m), 3 in (since 29m)
 
  data:
    pools:   1 pools, 32 pgs
    objects: 2 objects, 463 KiB
    usage:   80 MiB used, 120 GiB / 120 GiB avail
    pgs:     32 active+clean
