Logger fix

[edhzsz]

Issue #, if available: #7

Description of changes:

The Logger class is being monkey patched to use the telemetry logger when logging to stdout and/or stderr. There is a fallback to use the original logger when the logdev is not any of these targets (i.e. when it is a file name or IO object) but this fallback is not setting the names of the named parameters to the initialize call so it fails with error message:

"errorMessage": "wrong number of arguments (given 9, expected 1..3)",

Just adding the names to the named parameters fails with the error message stack level too deep which would indicate that the method is already being patched using Module#prepend. Using method_alias and Module#prepend on a method causes a conflict and eventually a stack overflow.

To be able to use prepend, I extracted the logger_patch to a separate module and then apply it with prepend.
