we need to check the wording with @oraNod
small commets, otherwise LGTM

Strings look fine to me, @dipguptaredhat Could you please externalize them to the assets/languages/en.json file? I think we'll be good to go then. Thanks.

@dipguptaredhat a couple of small latest changes

@dipguptaredhat Hi, hope you don't mind but I also pushed a commit to your branch for this one. A couple of questions, please. I've built this locally but don't see the cache availability from the console. Looking in the Cache Manager display table changes in this PR I would expect to see the availability there. Maybe I'm missing it. Could you provide a screenshot?

Also where is the "Done" button? I'm not sure where that displays or what the flow is for users to arrive to that modal. Cheers.

For setting a cache to Available, the cache need to have this configuration

{
  "distributed-cache": {
    "mode": "SYNC",
    "statistics": true,
    "encoding": {
      "key": {
        "media-type": "application/x-protostream"
      },
      "value": {
        "media-type": "application/x-protostream"
      }
    },
    "partition-handling": {
      "when-split": "DENY_READ_WRITES",
      "merge-policy": "NONE"
    }
  }
}

Also the cache need to be in DEGRADED_MODE,
curl -XPOST --digest -u "admin:password" "http://localhost:11222/rest/v2/caches/Test?action=set-availability&availability=DEGRADED_MODE"

Then the "Available" option will be shown as below

Thanks for the screenshots, @dipguptaredhat That's actually really helpful because I was trying to get caches into degraded mode by deliberately crashing nodes (was doing that for a different PR recently). I didn't realize you could also force a cache into degraded mode via REST.

Anyway that looks good to me but I think maybe "Done" should change to "OK" because it's more of a confirmation.

LGTM. Thanks @dipguptaredhat
