ldap authentication

[martinjrobins]

Fixes #132

This adds an option to authenticate via a ldap server, with logging in users as either normal users or admin depending on the ldap groups they are assigned to. This feature is controlled by a number of environment variables, which I've added to the example env file with some comments

It also adds some other quality-of-life stuff that I found useful, let me know if this is what you want:

• the develop settings include an option to use an sqlite database rather than postgres (I found this useful for developing outside a docker container)
• the develop settings add some debug logging
• the develop settings use python dotenv to load up a .env file if it exists (again I found this useful for developing outside a docker container)
• I've added docker-compose.yaml file for easy deployment of the client-direct app
• I've edited the Dockerfile to copy the current context dir rather than cloning from the master branch of the repo. This allows you to deploy from a custom branch or commit.

sorry the autoformatter (black) made this PR a bit noisy :(

there a quite a few lines in the ldap settings file that are not covered. I'm not sure how to test these without making an ldap server part of the CI. But I have tested it against an internal LDAP server and everything is working ok

Thanks @martinjrobins. It looks good to me. I'll try it out locally and look at some options for mock testing ldap on github actions.

[martinjrobins]

Hi @kwabenantim, have you had a chance to try this out? Let me know if there are any changes you would like me to make

[kwabenantim]

I'll try to finish this today @martinjrobins!
