Yossi Itigin 7cee60346e opal_progress: check timer only once per 8 calls

Reading the system clock on every call to opal_progress() is an
expensive operation on most architectures, and it can negatively affect
the performance, for example of message rate benchmarks.

We change opal_progress() to read the clock once per 8 calls, unless
there are active users of the event mechanism.

Fully support OMPI spawn options. Fix a bug in the round-robin mappers where we weren't adding nodes to the job map node array, and so resources were not released

Correct the comment in the default MCA param template - we do not support a param called "component_path". The correct syntax is "mca_base_component_path"
