Duplicating function signatures between server.py and server.pyi is
silly. This commit changes that by changing all `build_*` methods to
`get_*` methods and changing the `_make_dependency_method` to work work
as a descriptor that caches the produced value.
There are some changes in other files that were made to fix the typing
in server.py.
The CI appears to use the latest version of isort, which is a problem when isort gets a major version bump. Rather than try to pin the version, I've done the necessary to make isort5 happy with synapse.
secrets got introduced in python 3.6 so this class is not available
in 3.5 and before.
This now checks for the current running version and only tries using
secrets if the version is 3.6 or above
