Details of the problem
Several of the coll component's MCA variables are restrictively scoped as MCA_BASE_VAR_SCOPE_READONLY. A variable scoped READONLY can be set on the command line but not with the MPI_T tools interface. A change to MCA_BASE_VAR_SCOPE_ALL would enable these to be set by the MPI_T tools interface.
