feat(configuration): add error and warn log levels (#2050 )

This is so levels like warn and error can be used to exclude info or warn messages. Additionally there is a reasonable refactoring of logging moving the log config options to the logging key because there are a significant number of log options now. This also decouples the expvars and pprof handlers from the log level, and they are now configured by server.enable_expvars and server.enable_pprof at any logging level.

Time-based One-Time Password

Authelia uses time based one-time passwords as the OTP method. You have the option to tune the settings of the TOTP generation, and you can see a full example of TOTP configuration below, as well as sections describing them.

Configuration

totp:
  issuer: authelia.com
  period: 30
  skew: 1

Options

issuer

type: string {: .label .label-config .label-purple } default: Authelia {: .label .label-config .label-blue } required: no {: .label .label-config .label-green }

Applications generating one-time passwords usually display an issuer to differentiate applications registered by the user.

Authelia allows customisation of the issuer to differentiate the entry created by Authelia from others.

Period and Skew

The period and skew configuration parameters affect each other. The default values are a period of 30 and a skew of 1. It is highly recommended you do not change these unless you wish to set skew to 0.

The way you configure these affects security by changing the length of time a one-time password is valid for. The formula to calculate the effective validity period is period + (period * skew * 2). For example period 30 and skew 1 would result in 90 seconds of validity, and period 30 and skew 2 would result in 150 seconds of validity.

period

type: integer {: .label .label-config .label-purple } default: 30 {: .label .label-config .label-blue } required: no {: .label .label-config .label-green }

Configures the period of time in seconds a one-time password is current for. It is important to note that changing this value will require your users to register their application again.

It is recommended to keep this value set to 30, the minimum is 1.

skew

type: integer {: .label .label-config .label-purple } default: 1 {: .label .label-config .label-blue } required: no {: .label .label-config .label-green }

Configures the number of one-time passwords either side of the current one that are considered valid, each time you increase this it makes two more one-time passwords valid. For example the default of 1 has a total of 3 keys valid. A value of 2 has 5 one-time passwords valid.

It is recommended to keep this value set to 0 or 1, the minimum is 0.
