      Currently, the FTDC diagnostics directory is always relative to the data directory. If we allow it to be set via setParameter, we can then put these directories in a custom subdir of the data directory during testing. This will allow us to easily archive this data for help with understanding BFs.

      For reference:

      bencaimano@just-ben-book:/Users/bencaimano/git/mongodb/mongo [1]$ git grep kFTDCDefaultDirectory
src/mongo/db/ftdc/constants.h:constexpr StringData kFTDCDefaultDirectory = "diagnostic.data"_sd;
src/mongo/db/ftdc/ftdc_mongod.cpp:    dir /= kFTDCDefaultDirectory.toString();
src/mongo/db/ftdc/util.cpp:    base += "." + kFTDCDefaultDirectory.toString();
