Why I did it

Implements the debug grpc API as described in the HLD sonic-net/SONiC#1287.

Subscription preferences & capabilities for each oc-yang path is determined by individual yang handler code. There is no standard interface for clients to discover them. Hence a custom grpc is required.

How I did it

Added a new 'GetSubscribePreferences' grpc which accepts a list of yang paths and returns following subscription preferences for each:
- OnChangeSupported (if ON_CHANGE subscription will be accepted)
- TargetDefinedMode (mode to which TARGET_DEFINED will map to)
- WildcardSupported (if wildcard keys will be accepted)
- MinSampleInterval (minimum sample_interval accepted, in nanoseconds)

How to verify it

Added new gotests to call this grpc

Added a new 'GetSubscribePreferences' grpc which accepts a list of
yang paths and returns following subscription preferences for each:
 - OnChangeSupported (if on_change subscription will be accepted)
 - TargetDefinedMode (mode to which target_defined will map to)
 - WildcardSupported (if wildcard keys will be accepted)
 - MinSampleInterval (minimum sample_interval accepted, in nanos)

Accepts only translib managed yang paths. Uses the existing translib
API IsSubscribeSupported() to learn the preferences.

This rpc is defined in a new protobuf sonic_debug.proto. It defines
only one rpc 'GetSubscribePreferences' now. More debuggability actions
can be added in future.
