Feature: An option for fuse module to have the request queue length configurable.
Reason: With higher request queue length, fuse module can support more parallel fop requests (systemcalls). But when it is increased to higher value, there is more memory consumption, because more requests are queued up. There is no possible 'one value, fits all' type of solution here, hence we had to make it configurable to allow users to choose the right values based on use case, and their RAM size etc.
Result (if any): New option is implemented for fuse module to provide queue length during mount time.
