contrail-collector: schema change across versions hangs the collector

[Raj Reddy]

schema change across versions triggers 'update column family' and that cause the contrail-collector to hang [or take a very very long time] in update column family.

Need to investigate if this 'update' can be removed

for sql-like CFs, we allow schema to be changed, but we don't need
to call update_columnfamily, as that would unnecessarily try to
update all the data to new schema taking a whole lot of time.
for nosql CFs, we don't allow the schema to be changed, initialization
of collector will fail.
