Introduced extra parameter to ThreadPoolSvc initPool to allow increase the max allowed parallelism of TBB.

As discussed in https://its.cern.ch/jira/browse/ATR-26285 I added an additional parameter to initPool of the ThreadPoolSvc to allow for increasing the maximum allowed parallelism of TBB. This is set from the new maxParallelismExtra Gaudi property.

In order to do that I had to modify also the IThreadPoolSvc interface (would be great if someone could confirm if it is fine to modify it).

Thanks @ssottoco. This looks good to me. Can you just apply the formatting patch? (see the CI tab).

@leggett we will need this in ATLAS as a patch on top of Gaudi v38r0. Could you create a tag? I will then propagate it to our nightlies. Thanks.

approved this merge request

I cannot see the issue on the ATLAS JIRA, but can somebody explain why one cannot just artificially increase the value passed to ThreadPoolSize?
