Description

Currently Relbuilder.scan takes a single tableName string argument, however we'd like to use this to specify a sub-schema so we can use the Relbuilder to construct our queries across datasources.
The idea would be to change "scan(String tableName)" to "scan(String… tableNames)", and add "scan(Iterable<String> tableNames)".

This is as discussed here: http://mail-archives.apache.org/mod_mbox/calcite-dev/201605.mbox/%3CE4C0C38B-EDC2-4016-99C1-E7465AAC0C20%40apache.org%3E

Opened this ticket so that we can submit a PR with the change.
