- Add copyright headers to files that did not already have them
- Update the year to the last year the file was modified in files with
existing headers.
Mongoperf currently has a non-ASCII character in the file that causes a failure.
This commit rewords the description to remove the incriminating character.
Add a workload that runs mongoperf benchmark that measures I/O
performance on a MongoDB server. This workload assumes that mongoperf
is already installed.
