Collects Kibana Upgrade Assistant API output #680
Description
It would be useful to see if the cluster is ready for upgrade when the version of the cluster is at latest minor (like 7.17.x)
Instead of asking for the Kibana upgrade_assistant API separately, can we run this as part of the Kibana diagnostics?

GET <kibana host>:<port>/api/upgrade_assistant/status
example output:
{
"readyForUpgrade": false,
"cluster": [
{
"message": "Cluster deprecated issue",
"details":"You have 2 system indices that must be migrated and 5 Elasticsearch deprecation issues and 0 Kibana deprecation issues that must be resolved before upgrading."
}
]
