Config fixes (#432)
* Use the npm package `config` to load the config.

This is what was used prior to https://github.com/matrix-org/mjolnir/pull/347.
It was a nice idea motivated to drop a dependency that was confusing.
It was just never followed through and was underestimated how much disruption it would cause.
It was also believed that the library would mean there could only ever be one global copy of the config,
It was followed up by:
https://github.com/matrix-org/mjolnir/pull/369
https://github.com/matrix-org/mjolnir/pull/357
https://github.com/matrix-org/mjolnir/pull/429
https://github.com/matrix-org/mjolnir/pull/397/files
https://github.com/matrix-org/mjolnir/issues/365

For simplicity sake I am reinstating the library.
The practice of loading default.yaml by default is also dangerous
and has led to issues multiple times in #mjolnir:matrix.org.
It is a sample and not a default.

In a following commit I will be adding the ability to specify the
config to use from the cli.

* Allow config to be specified with an explicit cli argument.

* Update doc to transition away from old config handling

Mjolnir is available on the Docker Hub as [`matrixdotorg/mjolnir`](https://hub.docker.com/r/matrixdotorg/mjolnir).
Using docker, mjolnir can be setup and ran in either of two ways;
- Docker Run
- Docker Compose
Docker run will fire off a single-use container that is tied to your terminal's lifetime. (if you close the terminal, you shut down the bot)
Docker Compose can manage containers in the background, read a "compose" file, and automatically
recreate/restart relevant containers (upon `docker-compose up -d`) if they diverge from the file. It
can also easily read logs and manage the lifecycle of these containers. (start/stop/restart)
# Prerequisites
Before any other steps, a configuration file must be prepared.
Please go through [the sample configuration file's documentation](../config/default.yaml), download it, and rename it `production.yaml`.
You should go through and edit values to your liking, afterwards, pick a directory that'll be the root of all your mjolnir data files (i.e. `./mjolnir` from the home directory on your server), create a new directory called `config`, place the file there.
In short, please make sure that the mjolnir configuration exists under `./config/production.yaml` relative to the directory you've chosen, else mjolnir will not recognise it.
# Docker Run
Run the following command in your terminal, replace `./mjolnir` with the root directory of your config, if it is in another spot.
```bash
docker run --rm -it -v ./mjolnir:/data matrixdotorg/mjolnir:latest bot --mjolnir-config /data/config/production.yaml
```
# Docker Compose
Take the following file, and copy-paste it in `docker-compose.yml`;
```yaml
version: "3.3"
services:
mjolnir:
image: matrixdotorg/mjolnir:latest
restart: unless-stopped
volumes:
- ./mjolnir:/data
```
If you have pantalaimon installed, you can include it in this compose file as follows;
```yaml
version: "3.3"
services:
pantalaimon:
build: ./pantalaimon
container_name: pantalaimon
restart: unless-stopped
volumes:
- ./pantalaimon_data:/data
ports:
- 8008:8008
mjolnir:
image: matrixdotorg/mjolnir:latest
restart: unless-stopped
volumes:
- ./mjolnir:/data
```
**Note**: At the moment, pantalaimon does not have a Docker Hub image, so `./pantalaimon` needs to be the checked-out github repository, which you can do with `git clone https://github.com/matrix-org/pantalaimon`.
**Note**: In this configuration, you can access pantalaimon by using `pantalaimon` as a hostname, e.g. `http://pantalaimon:8080/` as `homeserverUrl`.
Replace `./mjolnir` (and optionally `./pantalaimon_data`) with the correct directories.
Then call `docker-compose up -d` while in the same directory as `docker-compose.yml` to pull, create, and start the containers.
- Use `docker-compose stop` to stop all containers, or `docker-compose stop mjolnir` to stop only the `mjolnir` container.
- Use `docker-compose restart mjolnir` to restart the mjolnir container, omit to restart all containers.
- Use `docker-compose down` to stop and remove all containers.
- Use `docker-compose logs` to display container logs, append `-f` to follow the logs in your terminal, append `--tail 100` to only show the latest 100 entries.
