* Dynamically control serilog configuration via command line parameters

|
|
* This works around the chicken and egg situation with configuring serilog via the command line.
|
|
* The logger needs to be configured prior to executing the parser, but the logger needs the parsed values
|
|
* to be configured. By using serilog.sinks.map we can defer configuration. We use a LogLevelSwitch to control the
|
|
* logging levels dynamically, and then we use a serilog enricher that has its state populated via a
|
|
* Spectre.Console CommandInterceptor
