Good idea. I'll add that once the current runs are green, to avoid triggering/waiting for unnecessary runs. |

Follow-up to #5993.
When 5.x nodes join from pre-5.x nodes, they end up with a default
subject_name(they get it in the join response, where it wasn't populated so had a default value). If they then try to renew the service cert, they'll cause a change in the service name. This is the minimal fix - ignore the serialisedsubject_namefield, and always extract it from the given service identity.This includes a small extension to the
lts_compatibilitytest to verify this behaviour. When run on the 5.x branch, this caused a failure without the C++ change, and passes with the C++ change.I'd like to make a more systematic cleanup of
identity.hto remove some dead code and simplify the constructor paths, but will do that separately from this minimal fix.
