[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.
