Jay Modi b234644035 Enforce Content-Type requirement on the rest layer and remove deprecated methods (#23146)
This commit enforces the requirement of Content-Type for the REST layer and removes the deprecated methods in transport
requests and their usages.

While doing this, it turns out that there are many places where *Entity classes are used from the apache http client
libraries and many of these usages did not specify the content type. The methods that do not specify a content type
explicitly have been added to forbidden apis to prevent more of these from entering our code base.

== Breaking changes in 6.0
This section discusses the changes that you need to be aware of when migrating
your application to Elasticsearch 6.0.
[float]
=== Indices created before 6.0
Elasticsearch 6.0 can read indices created in version 5.0 or above. An
Elasticsearch 6.0 node will not start in the presence of indices created in a
version of Elasticsearch before 5.0.
[IMPORTANT]
.Reindex indices from Elasticseach 2.x or before
=========================================
Indices created in Elasticsearch 2.x or before will need to be reindexed with
Elasticsearch 5.x in order to be readable by Elasticsearch 6.x. The easiest
way to reindex old indices is to use the `reindex` API.
=========================================
