[Docs] /tmp files cleanup issue when running the MI in Windows

[ruwanmadhusanka]

Description

When MI is doing a xslt transformation using the xslt mediator, if the input message size that is being transformed exceeds the synapse.temp_data.chunk.size, it will create a temporary file.

Once the transformation has been completed, if the transformed message size exceeds the synapse.temp_data.chunk.size, another temporary file will be created. At the moment, MI does not manually delete this temporary file as the reference for the content of this file can be used later, even after the xslt transformation. It is expected to be deleted at java.lang.Object.finalize() from the GC thread when there are no references to this temporary file.

We need to run a cron job to manually delete the files or else we have to add a cleanup task before starting the server. Then at every restart, the tmp folder will be cleaned up.

We need to add these details in xslt mediator docs.

Steps to Reproduce

Execute xslt transformation using the xslt mediator, which the input message size that is being transformed exceeds the synapse.temp_data.chunk.size.
