[belucid]

This is the master PR.

Also support and storage.

To test:

Go to the landing page with UTM params, e.g.

localhost:3559/?utm_campaign=foo&utm_term=bar&utm_source=foobar&utm_medium=message

• Clean your DB

• [x] Notice that the params are written to cookies

• [x] Notice that the URL was cleaned up

• Signup a new org via Slack

• [x] Check that the UTM cookies are gone

• [x] Check the org in the DB and see the UTM values

• [x] Check stabejo and see the UTM values

• Clean your DB again

• Repeat the steps above, but with an email signup, and only some of the UTM params, e.g.

localhost:3559/?utm_campaign=foo&utm_term=bar

• [x] Check that the UTM cookies are gone

• [x] Check the org in the DB and see the UTM values

• [x] Check stabejo and see the UTM values

• Clean your DB again

• Repeat the steps above, but with an email signup, and no UTM params, e.g.

localhost:3559/

• [x] Check that there are no UTM cookies

• [x] Check the org in the DB and see there are no UTM values

• [x] Check stabejo and see there is no mention of UTM values

• Merge branches
