Created a SoapClient Processor

[garadox]

I had a need to log a formatted SOAP request and response with Monolog. For security purposes I also need to sanitize some elements of the request and response.

I created a Processor for the SoapClient, but due to the SoapClient not being available globally I'm expecting the variable in the context array of the record. This is the part I like the least - if you have a recommendation for making this better i'll implement it.

I don't understand the goal of this processor

[garadox]

The goal is twofold:

• To obtain the XML for a SOAP request / response centrally for logging
• To apply any provided XPath rules to the XML for sanitizing sensitive elements before being logged.

The first case is not something which should be solved by a processor in the logger, but by a logger inside the SOAP client.
A processor is about adding extra information in all messages (this info being extracted from other source than the calling code generally, like the memory usage or a request token). Your implementation is weird: it adds the SOAP request and response inside other log messages. If there is no log calls, the request will not be logged. And it will not be logged for itself.

A simple way to implement the logging of request and response is to extend the SoapClient as described in http://stackoverflow.com/a/1729614
In such implementation, Monolog (or even better any PSR-3 logger) would be used inside the implementation of _logRequest and _logResponse (and these methods would perform the sanitizing logic)

Thanks for the pull request but I don't really feel like this is general purpose enough to warrant inclusion in monolog. @stof's feedback is also relevant in that a Processor might not really be the right way to do this, but it's probably technically working as is so feel free to keep this approach if you want in your project. I just don't see a need to include this in monolog.
