Add the possibility to query the file name ("location_href"?) of a package in the contents.

This simplifies the use of jq as we get directly the good href with the use of a GET query

 http :24817/pulp/api/v3/content/rpm/packages/?filename=name-version-release.arch.rpm

I prefer the query version than using jq

http :24817/pulp/api/v3/content/rpm/packages/ | jq -r '.results[] | select( .location_href == "name-version-release.arch.rpm")'

There could be a limitation when there are to much contents because the pagination prevents to look for all contents.

Just FYI, file name of a package is different than location_href. Location_href could include a path like "Packages/v/VirtualGL-devel-2.5.2-1.el7.x86_64.rpm".

Description from a duplicate: "Today, there is no filename filter on the package list endpoint. I think there are a couple fields (location_href or relative_path) that store a filename-like value for each package."
