Release 5.2.6

[fredericDelaporte]

Preparing the release. It currently accounts for pending PRs, async update and dependent transaction fix. If some of them are discarded or delayed to another release, this PR will have to be updated accordingly.

As written by @bahusoid here, some care should be taken when merging to master after the release:

When merging to master this change should be ignored. The following code is expected in master (no need to wrap in new List):

queryInfo.ResultToCache = queryCacheBuilder.Result;

Rebased, I will likely release it next Sunday.

#2111, in this release, has updated the documentation. But I do not intend to update it on nhibernate.info yet, because it is about a new feature, while we only publish minor version of the documentation, not release version. So updating the 5.2 documentation could be confusing for those attempting to use the feature with a 5.2.5 or below version of NHibernate. I think it should wait 5.3.

I agree - especially given that it was most likely for a really narrow use case anyway.
