When creating output file for collect_info, create a directory first and then zip the data

Currently, the collect_info creates a zip file of the individual files (membase.log, ns_server.log, stats.log) and when unzipping it, those files are extracted individually which makes it hard to track multiple collect_info files. Please put those into a directory first, and then zip them up so that the expansion will create a separate directory for each collect_info output.

i.e., A customer runs collect_info on three servers and then sends the 3 different output files (info1.zip, info2.zip, info3.zip) to support. Support then expands each of these files and there is no way to determine which infox.zip the files came from since they are all expanded into the same directory

Let me know if this makes sense...
