Make addLogContext accept a record with multiple params

[LoicPoullain]

Issue

• The signature of the method Logger.addLogContext is different from the other logging methods (info, warn, etc) in the way to pass the context (key/value vs record).
• When we want to add merge a object to the log context, it is tedious to do it because we need to call the method for each key.

Solution and steps

• Convert the method signature from Logger.addLogContext(key, value) to Logger.addLogContext(context)
