When loading columns from meta for a kudu table check that the key types match kudu's and are supported

Henry Robinson notes, regarding http://gerrit.cloudera.org:8080/#/c/1403/1/fe/src/main/java/com/cloudera/impala/catalog/KuduTable.java loc 156:

what happens if this TODO isn't done?

David replies:
not sure what this TODO means in general, particularly in this place. It seems that key type checking should either be done in a single place or relegated to Kudu. I've marked this as a follow up item to add a test for.
