Pull request #105 (2019-11-14 16:06:06)

Add blueprints freeze route
The blueprint freeze route `/blueprints/freeze/<names>` returns the blueprint info but each
package will be the package selected by depsolving. So, instead of the version being the version number with optional wildcards as /blueprints/info would provide, the version is of the form
`Version-Release.Arch`.
