Fusion Feature Requests

We observed that some tools, e.g. sentieon driver ... create many temporary files (>>1k) written and deleted during the run. Syncing these files with S3 takes a lot of computing time and often results in Fusion errors or process timeouts that require a process restart. I suggest creating a mechanism that will allow us to define (using pattern matching) which files are not synchronised by Fusion. This can be done via an ignore list, similar to the .gitignore file: https://git-scm.com/docs/gitignore

We used fusion but it took much longer time in I/O if there are too many (thousands) of input files. We would like to use non-fusion compenv for this task while using fusion compenv for other steps.
