Feature/7.x/update ll client

[Mpdreamz]

Update the 7.x branch to latest greatest from 7.x

[russcam]

Is this generated from 7.x or 7.6? Should it be generated from 7.6, if it's not?

[Mpdreamz]

Should be 7.x. We should discuss branching our next minor immediately after releasing our current minor.

Should have clarified in case it was ambiguous, Elasticsearch branch from which the REST specs are pulled, into the client 7.x branch.

Should be 7.x. We should discuss branching our next minor immediately after releasing our current minor.

Might Elasticsearch 7.x contain changes in it though that are not for the 7.6.0 client release e.g. APIs that are scheduled for Elasticsearch 7.7.0. Since Elasticsearch repository has cut a 7.6 branch, I think we should be pulling this into the client 7.x branch?

[codebrain]

My understanding is that we pull from elastic/elasticsearch 7.6 branch into our elastic/elasticsearch-net 7.x branch.

That way we avoid picking up anything in the elastic/elasticsearch 7.x branch that might be unfinished/in progress/destined for a later minor version.

Discussed offline 7.x will track 7.x from elastic/elasticsearch
