Support of constructor parameters

[vhatsura]

related to #167

Hey, guys! It's an early draft pull request with implementation of possiblity to create object via constructors with parameters. I will be appreciate if you can take a look and add your feedback

Thanks! Short on time but will try to loop back around. What was the situation in which you found yourself needing this? (I've seen several 👍)

In my case I use ExceptionAsObjectJsonFormatter from Serilog.Formatting.Elasticsearch. The formatter has a lot of arguments and sometimes we need to override them. This is why ability to configure constructor arguments in configuration is nice to have

@nblumhardt , what's the status on this? I just stumbled upon this problem today when introducing file logging in one of our solutions, and realizing I needed to set the renderMessage argument on JsonFormatter to true.

Would be really useful to have first-class support for configuring complex/abstract instances with parameters in config files.

@julealgon for now, you might want to use a workaround such as the one described in
serilog/serilog-sinks-console#28

or follow indications in https://github.com/tsimbalar/serilog-settings-comparison/blob/master/docs/README.md#interfaces-and-abstract-classes , and make a Formatter configured the way you want it either as :

• a custom class with a default constructor
• a static property on your own type

Hello @tsimbalar. How's this solving the problem where there is a need to configure a TextFormatter with constructor arguments (non-parameterless constructor)?

[tsimbalar]

@tzographos you're right, there is nothing about this in serilog/serilog-sinks-console#28 ... no idea what I meant back then 🤔

Hi @vhatsura ,
Sorry for the long delay on this one. The feature become high requested with the new ExpressionTemplate.

Are you still interested to work on this? I made a workable sketch for a complete solution, but first would like to know your opinion if you still interested.

Ok, I've just created the new one with additional features. Feel free to comment/review :)
