1168602 - fix missing /usr/share/pulp-rpm/pulp_distribution.xsd in the spec file
1165355 - Sanitize checksum types.

SHA and SHA-1 are the same checksum algorithm, but Pulp considered them
to be separate algorithms. This commit ensures that Pulp no longer
stores the SHA-1 algorithm as "sha" in the database, and it also
contains a migration that resolves existing "sha" objects.
