refactor(configuration): use key log instead of logging (#2072)
* refactor: logging config key to log

This refactors the recent pre-release change adding log options to their own configuration section in favor of a log section (from logging).

* docs: add step to getting started to get the latest tagged commit

This is so we avoid issues with changes on master having differences that don't work on the latest docker tag.

* test: adjust tests

* docs: adjust doc strings

# Logging
The logging section tunes the logging settings.
## Configuration
```yaml
log:
level: info
format: text
file_path: ""
keep_stdout: false
```
## Options
### level
<div markdown="1">
type: string
{: .label .label-config .label-purple }
default: info
{: .label .label-config .label-blue }
required: no
{: .label .label-config .label-green }
</div>
Defines the level of logs used by Authelia. This level can be set to `trace`, `debug`, `info`, `warn`, or `error`. When
setting level to `trace`, you will generate a large amount of log entries and expose the `/debug/vars` and
`/debug/pprof/` endpoints which should not be enabled in production.
```yaml
log:
level: debug
```
### format
<div markdown="1">
type: string
{: .label .label-config .label-purple }
default: text
{: .label .label-config .label-blue }
required: no
{: .label .label-config .label-green }
</div>
Defines the format of the logs written by Authelia. This format can be set to `json` or `text`.
```yaml
log:
format: json
```
#### JSON format
```
{"level":"info","msg":"Logging severity set to info","time":"2020-01-01T00:00:00+11:00"}
{"level":"info","msg":"Authelia is listening for non-TLS connections on 0.0.0.0:9091","time":"2020-01-01T00:00:00+11:00"}
```
#### Text format
```
time="2020-01-01T00:00:00+11:00" level=info msg="Logging severity set to info"
time="2020-01-01T00:00:00+11:00" level=info msg="Authelia is listening for non-TLS connections on 0.0.0.0:9091"
```
### file_path
<div markdown="1">
type: string (path)
{: .label .label-config .label-purple }
default: ""
{: .label .label-config .label-blue }
required: no
{: .label .label-config .label-green }
</div>
Logs can be stored in a file when file path is provided. Otherwise logs are written to standard output. When setting the
level to `debug` or `trace` this will generate large amount of log entries. Administrators will need to ensure that
they rotate and/or truncate the logs over time to prevent significant long-term disk usage.
```yaml
log:
file_path: /config/authelia.log
```
### keep_stdout
<div markdown="1">
type: boolean
{: .label .label-config .label-purple }
default: false
{: .label .label-config .label-blue }
required: no
{: .label .label-config .label-green }
</div>
Overrides the behaviour to redirect logging only to the `file_path`. If set to `true` logs will be written to both
standard output, and the defined logging location.
```yaml
log:
keep_stdout: true
```
