Add validation while updating CompatibilityMode setting

[ltaragi]

Description

This PR implements the following two checks while updating the CompatibilityMode setting:

• Don't allow changing (STRICT <--> MIXED) the CompatibilityMode if all the nodes in the cluster are not of the same open search version
• Don't allow switching to STRICT mode if the cluster contains both remote and non-remote nodes

This was done as follows:

• TransportClusterUpdateSettingsAction receives both the ClusterUpdateSettingsRequest and ClusterState
• The requested new value for CompatibilityMode can be found inside the ClusterUpdateSettingsRequest object
• Information on nodes like remote store enabled nature and opensearch version can be found inside the ClusterState object
• validateCompatibilityModeSettingRequest ensures the required checks by in turn calling validateAllNodesOfSameVersion and validateAllNodesOfSameType
