mds: limit maximum number of caps held by session

This is to prevent unsustainable situations where a client has so many
outstanding caps that a linear traversal/operation on the session's caps takes
unacceptable amounts of time.

(cherry picked from commit 48ca097a9f537545b4b0c864ebb8c5e81d821098)
