07d5907ecd aurweb.auth: add user credentials and matcher functions
This clones the behavior already present in the PHP implementation,
but it uses a global dict with credential constant keys to
validation functions to determine if a given user has a credential.

a33d076d8b add passreset routes
Introduced `get|post` `/passreset` routes. These routes mimic the
behavior of the existing PHP implementation, with the exception of
HTTP status code returns.

Routes added:
    GET /passreset
    POST /passreset

Routers added:
    aurweb.routers.accounts

* On an unknown user or mismatched resetkey (where resetkey must ==
  user.resetkey), return HTTP status NOT_FOUND (404).
* On another error in the request, return HTTP status BAD_REQUEST (400).

Both `get|post` routes requires that the current user is **not**
authenticated, hence `@auth_required(False, redirect="/")`.

+ Added auth_required decorator to aurweb.auth.
+ Added some more utility to aurweb.models.user.User.
+ Added `partials/error.html` template.
+ Added `passreset.html` template.
+ Added aurweb.db.ConnectionExecutor functor for paramstyle logic.
  Decoupling the executor logic from the database connection logic
  is needed for us to easily use the same logic with a fastapi
  database session, when we need to use aurweb.scripts modules.

At this point, notification configuration is now required to complete
tests involved with notifications properly, like passreset.
`conf/config.dev` has been modified to include [notifications] sendmail,
sender and reply-to overrides. Dockerfile and .gitlab-ci.yml have been
updated to setup /etc/hosts and start postfix before running tests.

* setup.cfg: ignore E741, C901 in aurweb.routers.accounts

These two warnings (shown in the commit) are not dangerous and a bi-product
of maintaining compatibility with our current code flow.

56f2798279 add aurweb.auth and authentication to User
+ Added aurweb.auth.AnonymousUser
    * An instance of this model is returned as the request user
      when the request is not authenticated
+ Added aurweb.auth.BasicAuthBackend
+ Add starlette's AuthenticationMiddleware to app middleware,
  which uses our BasicAuthBackend facility
+ Added User.is_authenticated()
+ Added User.authenticate(password)
+ Added User.login(request, password)
+ Added User.logout(request)
+ Added repr(User(...)) representation
+ Added aurweb.auth.auth_required decorator.

This change uses the same AURSID logic in the PHP implementation.

Additionally, introduce a few helpers for authentication,
one of which being `User.update_password(password, rounds = 12)`
where `rounds` is a configurable number of salt rounds.

a836892cde aurweb.db: add query, create, delete helpers
Takes sqlalchemy kwargs or stanzas:

query(Model, Model.Column == value)
query(Model, and_(Model.Column == value, Model.Column != "BAD!"))

Updated tests to reflect the new utility and a comment about upcoming
function deprecation is added to get_account_type().

From here on, phase out the use of get_account_type().

+ aurweb.db: Added create utility function
+ aurweb.db: Added delete utility function

The `delete` function can be used to delete a record by search
kwargs directly.

Example:
    delete(User, User.ID == 6)

All three functions added in this commit are typically useful to
perform these operations without having to import aurweb.db.session.
Removes a bit of redundancy overall.

8a47afd2ea add aurweb.models.user.User
+ Added aurweb.models.user.User class. This is the first example
  of an sqlalchemy ORM model. We can search for users via for example:
  `session.query(User).filter(User.ID==1).first()`, where `session` is
  a configured `aurweb.db.session` object.
+ Along with the User class, defined the AccountType class.
  Each User maintains a relationship to its AccountType via User.AccountType.
+ Added AccountType.users backref.
