Kibana alerting is going to be built using API Keys, and should be
permitted on a basic license.
This commit moves API Keys (but not Tokens) to the Basic license
Relates: elastic/kibana#36836
Backport of: #42787
This is modelled on the qa test for TLS on basic.
It starts a cluster on basic with security & performs a number of
security related checks.
It also performs those same checks on a trial license.
