Upstream PR will cause options to be properly set.

Upstream PR will cause options to be properly set.

@frost-intel, can you, please, clarify how your PR relates with the upstream PR mentioned above? Is upstream PR a prerequisite to this one or vice versa? i.e. which one should be merged first or they are independent?

@dvrogozh Both PRs are necessary to fix a specific bug, where the ProcessGroupXCCL::Options was not being set properly when passed as an argument. However, the two PRs are not dependent on each other. There are two different bugs which have the same effect. The upstream PR fixes the issue of Options not being writable, and this PR fixes a problem with the initialization list order and the proper value not being set before it was used by createLogPrefix.
