[ofiwg] libfabric rc1 releases v1.14.1rc1 and v1.15.0rc1 now available

[Hefty, Sean]

Release candidates for libfabric versions v1.14.1rc1:

https://github.com/ofiwg/libfabric/releases/tag/v1.14.1rc1

and v1.15.0rc1:

https://github.com/ofiwg/libfabric/releases/tag/v1.15.0rc1

are now available.  As requested at a previous ofiwg meeting, I created a new v1.15.x branch after tagging v1.15.0rc1.  Development on the mainline can continue as normal.  Any patches that need to be included in the final v1.15.0 release will need to be cherry-picked into v1.15.x.

Thanks,
- Sean
