Initial SWGS models and upload

[Istaisa]

This is very much a work in progress but it puts down the fundamentals and I want to try and avoid one giant one at once.

Included in this pull request:

• The basic setup/settings changes etc. for an SWGS app
• Most of the models and their associated admin pages
• A run and patient analysis web page - currently exclusively for dev work
• an import script which puts the test information, qc information and snvs in to the database

Test data and running the imports: After making migrations, load the fixtures: manage.py loaddata swgs/fixtures/setup_fixtures.json Then import te data: manage.py import_wgs --patient_json test_patient_info.json --qc_json test_overall_qc.json --germline_snv_json test_germline_snv.json --somatic_snv_json test_somatic_snv.json

Example jsons are available here: https://github.com/AWGL/dragenswgs_post_processing/tree/vcf_to_json/tests/test_data/test_svd_files from the cell lines data. These will get moved in to SVD once they're finalised I've got some clinvar and cancer hotspots tweaked to make.

Added basic CSV download functionality - closes #131 . Currently it downloads everything displayed on webpage, I can add in clinvar, cancer hotspots etc. as well, I just need to update my SVD test dataset for those. We can comment out the SWGS link from the main bar to put it live in the background. Also to add: I'll do an upload script refactor once we've got everything going in as there is some code duplication due to the different germline/somatic models.

All inline comments resolved.

• Managers - yeah we'll talk about these. They're going to get involved again when the fixtures get more complex but yes for now they're not used - they were in v1 of my test data but I've turned everything to jsons since. If we leave for now I'll update or delete as appropriate when SNVs are in a more useable state
• I was also thinking one main homepage
• Breadcrumbs: definitely open to any HTML suggestions that is not my strong suit. Maybe if we do a HTML/design sitdown further down the line
• Repetition - agree, i'll fix it when all the code's in place and I know what I'm refactoring
• Agree with the logging comments. I need to add clinvar and cancer hostpots as these have been updated in the pipeline since, I'll add logging comments when I do that
• There will be so many more tests
