HYPERDX_LOG_LEVEL sets the level, not max level, of API HTTP messages

[wschroeder]

The referenced commit and line introduced a bug wherein whatever the MAX_LEVEL is set to, expressWinston submits logs at that level. It is a level setter, not a max level setter.

I'm seeing this problem too. A fix would be great.

Example: If I set HYPERDX_LOG_LEVEL to "warn", the API logs begin to be logged at the warn level.

This should be fixed in v2.7.0
