Support simple rest provider for OpenApi admin

[FaritSlv]

Hi all.

Will there be "Simple Rest Provider" support for OpenApi admin?

At the moment, OpenApi admin works according to the scheme:

Method	API calls
getList	GET http://my.api.url/posts?sort=["title","ASC"]&range=[0, 24]&filter={"title":"bar"}
getOne	GET http://my.api.url/posts/123
getMany	GET http://my.api.url/posts?filter={"id":[123,456,789]}
getManyReference	GET http://my.api.url/posts?filter={"author_id":345}
create	POST http://my.api.url/posts
update	PUT http://my.api.url/posts/123
updateMany	Multiple calls to PUT http://my.api.url/posts/123
delete	DELETE http://my.api.url/posts/123
deleteMany	Multiple calls to DELETE http://my.api.url/posts/123

And the api-platform/admin sends data according to this scheme, and the kernel ignores the filters for getList, getOne, getMany, getManyReference.
