[RELEASE] Release 2.10.0

[reta]

Release 2.10.0 with multiple fixes and generic HTTP client.
@VachaShah @dblock any objections?

I'd like to make sure we're on the same page with #910 (comment) before releasing, since it would be a breaking change to revert the behavior in the future version. I opened #927 to discuss.

This release contains new features, so it should also be 2.10, right @reta?

Now yes, I was thinking to have 2.9.2 release without generic client, but going 2.10.0 make sense now, thanks @dblock !
