Bug Description

On contrail-api startup, there is a walk conducted on OBJ_UUID_TABLE in cassandra DB and the contents transformed + populated to ifmap-server.

In large scaled systems this walk is inefficient as there is a round-trip to cassandra to read each object. Optimize this by reading collection of objects based on type from cassandra.

config-perf: improve startup time by fetching object collections.

Instead of fetching objects one at a time from DB, fetch them
type at a time. Reducing the round-trips to cassandra improves
the startup significantly.
