Enable filtering of log output

[simoami]

Feature: Log filtering
  In order to utilize log efficiently
  As a Mimik user
  I would like to be able to filter log output

  Scenario: No filters
    Given that mimik is installed
    When user executes the `mimik run --debug` command
    Then use will see log output
    And displayed logs should not be filtered

  Scenario: Wildcards
    When user executes the `DEBUG=* mimik run --debug` command
    Then use will see log output
    And displayed logs should not be filtered

  Scenario: Comma-separated filters
    When user executes the `DEBUG=command,runner mimik run --debug` command
    Then use will see log output
    And displayed logs should only show logs for command and runner

  Scenario: Filter prefixes
    When user executes the `DEBUG=driver:base run --debug` command
    Then use will see log output
    And displayed logs should only show logs for the BaseDriver
    When user executes the `DEBUG=driver:* run --debug` command
    Then use will see log output
    And displayed logs should only show logs for all active drivers
