pool: allow more data chunks in an ec pool

The schema has a limit of 9 data and 9 coding chunks in an EC pool. While not typically recommended, more data chunks may be desired. Ceph does not have a limit, so we match the behavior and also allow any number of desired chunks to be specified. Signed-off-by: Travis Nielsen <tnielsen@redhat.com>
