Improve DNS table models 

This commit adds Meta information and __str__ methods  to all DNS table
models. The new methods are now covered with new tests. The new
constants DNS_DOMAIN_METADATA_KINDS and DNS_TSIG_KEY_ALGORITHMS are
defined and used in the DNSDomainMetadata and DNSTSIGKey models. A
matching database schema migration is added.
