there are performance issues with transactions that both do
DDL and change very large numbers of rows.

Don't acquire table locks in command filter.
The filter_AlterTableStmt() function was using
AlterTableGetLockLevel(astmt->cmds) to determine lock level which to use
on relation being ALTERed. This can cause deadlock against bdr_apply
when the apply is trying to catch up with changes from another node to
synchronize cluster for a DDL lock - any concurrent DML that is coming
from another node will never get the row lock grant because the table is
already locked by the backend performing the ALTER on it.
We now get the relid with NoLock which should be safe as we don't allow
concurrent DDL anyway so the table can't change under our hands.
