Description of the Change

This PR introduces the ability to utilize all valid query parameters of /api/packages on /api/packages/search.

This now means you can search for a package name while also:

• Showing results that support a specific file extension
• Showing results that are either consumers or providers of a specific service
• Showing results that are consumers or providers of a specific service and version
• Showing results results of a specific owner

While of course still being able to:

• Sort the packages in the desired direction
• Get the specific page
• Sort the packages in a particular direction

Of course, if preferred, you are still able to get a full list of packages without any search.

This means this is a fully backwards compatible method of adding far more capabilities to the package searching.

Technical Notes:

• This PR expands the work done by @savetheclocktower of utilizing _Clause() functions within getSortedPackages() to elegantly and easily extend the accepted functionality of the function. Using this I was able to add the query query parameter to the function.
• As it's no longer used the original simpleSearch() function has been removed in favour of getSortedPackages().
