Added support for importing keys via primary/security mirror clauses (#882)

Presently, mirror keys cannot be associated with primary/security
mirrors.  Unfortunately, this prevents use of Landscape-managed
package mirrors as the mirror key for the Landscape-hosted repository
cannot be provided.

This patch allows the same key-related fields usable on "sources"
entries to be used on the "primary" and "security" entries as well.
