Set log level based on MDC values

This can be used to change the log level based on MDC valus. E.g. change log levels for specific users/services etc.

Properties

Property	Description	Default
`logger.mdc.enabled`	MDC enabled?	`true`
`logger.mdc.<key>`	MDC key to use	``
`logger.mdc.<key>.key`	MDC key override, see complex example below for usage	`<key>`
`logger.mdc.<key>.level`	log level to use	`TRACE`
`logger.mdc.<key>.loggers`	passlist of logger names, matches all loggers if empty	`[]`
`logger.mdc.<key>.values`	values for matching MDC key, matches all values if empty	`[]`

Examples

Minimal configuration that logs everything with TRACE if MDC principal is present:

logger:
  levels:
    io.kokuwa: INFO
  mdc:
    principal: {}

Configuration that logs everything with TRACE for logger io.kokuwa if MDC gateway matches one value:

logger:
  levels:
    io.kokuwa: INFO
  mdc:
    gateway:
      loggers:
        - io.kokuwa
      values:
        - 257802b2-22fe-4dcc-bb99-c1db2a47861f
        - 0a44738b-0c3a-4798-8210-2495485f10b2

Complex example with setting different values for different values/logger:

logger:
  levels:
    io.kokuwa: INFO
  mdc:
    gateway-debug:
      key: gateway
      level: DEBUG
      loggers:
        - io.kokuwa
      values:
        - 6a1bae7f-eb6c-4c81-af9d-dc15396584e2
        - fb3318f1-2c73-48e9-acd4-a2be3c9f9256
    gateway-trace:
      key: gateway
      level: TRACE
      loggers:
        - io.kokuwa
        - io.micronaut
      values:
        - 257802b2-22fe-4dcc-bb99-c1db2a47861f
