db: compaction strategy changes via alter table must have immediate effect

Browse Source 
At the moment, compaction strategy changes via ALTER TABLE have no effect until
node restart.

Tomek says: "Statements of the following form should have immediate effect:
ALTER TABLE t WITH compaction = { 'class' : 'LeveledCompactionStrategy' };"

Fixes #877.
