Support rpm name substring filtering

[jlsherrill]

Is your feature request related to a problem? Please describe.

When listing rpms, i'd love to be able to filter based on the substring of a package name:

Describe the solution you'd like

GET /pulp/api/v3/content/rpm/packages/?name_match="kernel"

using a wildcard of some sort would allow the user to control if its only at the start "kernel*" or anywhere in the name "kernel"

Describe alternatives you've considered
The less flexible version would be:

GET /pulp/pulp/api/v3/content/rpm/packages/?name_substring="kernel"

Additional context
This would allow for easier filtering to find matches for a user's search.

The less flexible version is trivial, a one line change we can implement in seconds. The full "matching" would be more challenging, I think. Would it be useful to go ahead and make the first available as an interim measure?

[jlsherrill]

you could always support name_substring & name_startswith separately. That probably covers most all cases

[dralley]

I can do that. Should we keep this open in hopes of a full implementation later?

[jlsherrill]

I think if both of those simple filters are implemented, this issue could be closed.
