Summary (updated)

Allowed to pass total resources in 'UpdateSlaveMessage'.

Bugs: MESOS-7757

Repository: mesos

Description (updated)

This commit both extends the existing 'UpdateSlaveMessage' proto

To distinguish updates to 'oversubscribed_resources' from updates to
'total_resources' the message now contains a 'type' field to allow
disambiguation among an empty list of resources and an unset list of
resources. For backwards-compatibility we assume whenever the type
field was not set that caller intended to use the
'oversubscribed_resources' field as opposed to the 'total_resources'

Currently, passing 'total_resources' is handled neither in the master
nor the default allocator; we will implement this in a subsequent
