Description

Currently, due to limitations in the Kudu API, Impala imposes a number of constraints on new columns:
1. nullable columns can't have default values (KUDU-1747)
2. no encoding/compression/block size can be specified (KUDU-1746)
Now that Kudu jiras have been resolved, we should remove these constraints on the Impala side.
