Adding limit to total size of uploaded files from analysis

Thanks for contributing! But first: did you read our community guidelines?

What I have added/changed is:

If you pass max_total_size_of_uploaded_files=[0|int>0] as a task option, the analyzer will only upload files from analysis up until the total size of these files could exceed the limit.

The goal of my change is:

There are samples such as this that behave in such a way that the Cuckoo analyzer ends up uploading ~1.3Gb of files and ~2.8Gb of logs to the resultserver, which may cause issues depending on how you are using Cuckoo's analysis post-analysis (ex. Using the REST API to retrieve a tarball that contains all of this!💀). Therefore, I propose that there should be an option to limit the total size of files that are to be uploaded from analysis.

What I have tested about my change is:

Manual testing.

Let me know what you think!
