Description

1. The API calls to perform all backend operations needs to provide a “source” element in the “RequestInfo” properties to identify the logical level at which the operation is executed.

Possible levels:

{CLUSTER, SERVICE, HOST_COMPONENT, HOST}

Note: Service component is analogous to Service, no level specification needed at the moment.

2. The current states for Maintenance mode will be modified to add more context to the IMPLIED state.
