HAWQ-80. Support dynamic relation distribution type in gpopt
If there are 3 hash distributed tables in a query, each has a different
buckets number, say 8, 24 and 64, the resource negotiator will allocate
max(8,24,64)=64 vSegs. In this case, the tables with buckets number 8 and 24
will need to be regarded as random distributed table during planning.
