* Docs: add missing PR submission process how-tos
The documentation says that in order to submit a pull request you have to run the linter and links to [Run the linters](https://matrix-org.github.io/synapse/latest/development/contributing_guide.html#run-the-linters). IMO "Run the linters" should explain that development dependencies are a pre-requisite.
I also included `pip install wheel` which I had to run inside my virtual environment on ubuntu before I `pip install -e ".[all,dev]"` would succeed.
- Use sytest:bionic. Sytest:latest is two years old (do we want
CI to push out latest at all?) and comes with Python 3.5, which we
explictly no longer support. The script now runs under PostgreSQL 10
as a result.
- Advertise script in the docs
- Move pg testing script to scripts-dev directory
- Write to host as the script's exector, not root
A few changes to make it speedier to re-run the tests:
- Create blank DB in the container, not the script, so we don't have to
`initdb` each time
- Use a named volume to persist the tox environment, so we don't have to
fetch and install a bunch of packages from PyPI each time
