Piotr Smaron c73d0ffbaa cql: sum of abs RFs diffs cannot exceed 1 in ALTER tablets KS ...

Tablets load balancer is unable to process more than a single pending
replica, thus ALTER tablets KS cannot accept an ALTER statement which
would result in creating 2+ pending replicas, hence it has to validate
if the sum of absoulte differences of RFs specified in the statement is
not greter than 1.
