    [FLINK-7583] [REST] Use static constant for CONTENT_TYPE header

    ## What is the purpose of the change
    This PR introduces a static constant to be used as the HTTP CONTENT_TYPE header value.
This ensures that we only allocate the string once, and that the client/server always use
the same value.
    ## Brief change log
    * Add `RestConstants` class
    * Add `REST_CONTENT_TYPE` constants
    *  modify `RestClient` and `AbstractRestHandler` accordingly
    ## Verifying this change
    This change is a trivial rework / code cleanup without any test coverage.

allocate a separate string for each request/response. We should instead use a static constant.
