This adds a force-merge step to the searchable snapshot action, enabled by default,
but parameterizable using the `force_merge-index" optional boolean.
eg.
```
PUT _ilm/policy/my_policy
{
"policy": {
"phases": {
"cold": {
"actions": {
"searchable_snapshot" : {
"snapshot_repository" : "backing_repo",
"force_merge_index": true
}
}
}
}
}
}
```

Super minor, but we allow force merge in "hot", so maybe we should just say
If the managed index was already force merged using the
<<ilm-forcemerge, force merge action>> in a previous action
the `searchable snapshot` action force merge step will be a no-op.

We might also want to mention that force merging is best effort, since it's possible for it to fail (and we still continue)
