Add a log Header

[christophekumor]

Param to add a header to the log file.

we'll have to define what we want in this header.

[lazywinadmin]

in most case i see people use this to log the environment/context
Version of powershell, path of script, current user, etc...

I would keep the header and footer parsable. example

<datetime> <delimiter> <messagetype> <delimiter> <source><delimiter><message>
example:

2019/06/25.08:34:00UTC;INF;HEADER;Using PowerShell version: 6.2
2019/06/25.08:34:01UTC;INF;HEADER;current user: mydomain\lazywinadmin
2019/06/25.08:34:01UTC;INF;MAIN; define var....
2019/06/25.08:34:01UTC;INF;MAIN; connect to db
2019/06/25.08:34:01UTC;INF;MAIN; perform task
2019/06/25.08:34:01UTC;INF;MAIN; done
2019/06/25.08:34:01UTC;INF;FOOTER; script completed in 1sec

ok for a header but as proposed @lazywinadmin with the same format as the log itself.
I hate having a log with header, log then footer :-) like that

i don't like
Header
Using PowerShell version: 6.2

The main problem here is that we create a fixed format.
We should have a dynamic format or at least a format we can extend to use other log containers like Json, Win Event ...

as i said i don't like header and footer on log file so for me is not useful ;-)
