func NewActivation(config ActivationLoggerConfig) (Logger, error)

NewActivation creates a new activation key logger. This logger kind can be used on command line tools to improve situations in which log filtering using other command line tools like grep is not sufficient. Due to certain filter mechanisms this Logger implementation should not be used in performance critical applications. The idea of the activation key logger is to have a multi dimensional log filter mechanism. This logger here provides three different features which can be combined and used simultaneously at will.

Filtering arbitrary key-value pairs. The structured nature of the Logger
interface expects key-value pairs to be logged. The activation key logger
can be configured with any kind of activation key-pairs which, when
configured, all have to match against an emitted logging call, in order
to be dispatched. In case none, or not all activation keys match, the
emitted logging call is going to be ignored.

Filtering log levels works using the special log levels debug, info,
warning and error. The level based nature of this activation mechanism is
that lower log levels match just like exact log levels match. When the
Logger is configured to activate on info log levels, the Logger will
activate on debug related logs, as well as info related logs, but not on
warning or error related logs.

Filtering log verbosity works similar like the log level mechanism, but
on arbitrary verbosity levels, which are represented as numbers. As long
as the configured verbosity is higher or equal to the perceived verbosity
obtained by the emitted logging call, the log will be dispatched.
