Fields that can be set by the API caller - read/write

TTL MS, or "time to live", is how long a cached item will stay in the cache before it is removed (in milliseconds)

If UseDefaultTTL is enabled, then the TTLQueriesMS and TTLResourcesMS in this object is always sent as the default TTL located in grafana.ini
