Allow system log to be triggered from a controller or model

[nohponex]

• One approach is to define the phramework callback step in register method and allow the modification of $additionalParameters argument

The modification of $additionalParameters might be impossible due to immediate definition of the callbacks.

We might have to call the register method the moment we need to defined the additional log information or it might be possible to change the callback definitions to use the provided arguments later in execution

@alkallio there is an issue with the solution we discussed, "changing phramework's callback step in register method"

The definition of callback also require invoked controller and method which are used in addition with matrix settings. Although we need to figure out a way to have triggered system log entries in a uniform way.

This might require additional modifications and restructuring of SystemLog class, but it wont affect the current projects that are using SystemLog
