Add endpoint to create or update a package set #205

[404-geek]

I have crafted an api for updating a package set with purl entry.

Below is the approach which I have taken.

Take a list of packages (where each item is a dictionary containing PURL and content_type).

If uuid is given then all purls will be added to package set if it exists else a new set would be created and all the purls will be added to that new set.

Note: There is also a slight addition to the logic where a purl already exists in the database
and so there are no changes done to the purl entry it is passed as it is.

Request example:

{
          "purls": [
            {"purl": "pkg:npm/[email protected]", "content_type": 1}
          ],
          "uuid" : "b67ceb49-1538-481f-a572-431062f382gg"
        }

Please feel free to suggest any changes to the approach or if anything false has been assumed/coded.

@404-geek Thanks for the PR! Can you make a test for this new view?

@JonoYang I have added some test cases for the view in packagedb/tests/test_api.py. Please review the changes.

@404-geek Thanks for the revisions! I left a comment about using the text label for content_type choices instead of the integer value when updating a package set

[JonoYang]

Add one more test for when an invalid or nonexisting uuid is given to the API.

[404-geek]

Added a test for non exisiting uuid

@404-geek LGTM, thanks!
