Not pulling sample document from system.profile

[ciudilo]

Previously we would pull a sample document from system.profile collection which could contain regexes.
Regexes sometimes are not processed correctly and cause promblems for proactiveDB analysis.

Any document in any collection can contain regexes, it's just that system.profile is generally more likely to contain them. Is the issue here SERVER-11771 (or similar), or something else? Would it be better to see if we can more generically remove from the output any regexes that the shell can't handle? eg. convert them to a { $regex: "...", $options: "..." } subdocument?
