  1. coll tuned dynamic rules file alltoall_algorithm_max_requests 

    Teach the dynamic rules file reader to look for the
alltoall_algorithm_max_requests tuning parameter.  To keep the dynamic rules
file format backward compatible the alltoall_algorithm_max_requests is
optional. When not present in the rule definition the value of the
corresponding MCA variable is used instead.

Resolves open-mpi#12589

  2. coll tuned add version identifier to the rules file 

    the version identifier is optional but when provided it  must have the
following format and must appear on the first line.`rule-file-version-N`
where N is an unsigned integer. Older versions of the
parser will fall back to fixed decision mechanism when this line is
present. Version 1 is the original format, Version 2 has support for
optional coll_tuned_alltoall_algorithm_max_requests specification.
