Mingyu Chen cefe1794d4 Fix bug that replicas of a tablet may be located on same host (#1517 )

Doris support deploy multi BE on one host. So when allocating BE for replicas of
a tablet, we should select different host. But there is a bug in tablet scheduler
that same host may be selected for one tablet. This patch will fix this problem.

There are some places related to this problem:

1. Create Table
    There is no bug in Create Table process.

2. Tablet Scheduler
    Fixed when selecting BE for REPLICA_MISSING and REPLICA_RELOCATING.
    Fixed when balance the tablet.

3. Colocate Table Balancer
    Fixed when selecting BE for repairing colocate backend sequence.
    Not fix in colocate group balance. Leave it to colocate repairing.

4. Tablet report
    Tablet report may add replica to catalog. But I did not check the host here,
    Tablet Scheduler will fix it.
