Test schema compatibility against all schemas under a subject
POST/compatibility/subjects/:subject/versions
Test input schema against a subject's schemas for compatibility, based on the configured compatibility level of the subject. In other words, it will perform the same compatibility check as register for that subject. The compatibility level applied for the check is the configured compatibility level for the subject (http:get:: /config/(string: subject)). If this subject's compatibility level was never changed, then the global compatibility level applies (http:get:: /config).

Response Headers
X-Request-Id
The unique identifier for the API request.
X-RateLimit-Limit
The maximum number of requests you're permitted to make per time period.
X-RateLimit-Remaining
The number of requests remaining in the current rate limit window.
X-RateLimit-Reset
The relative time in seconds until the current rate-limit window resets.
Important: This differs from Github and Twitter's same-named header which uses UTC epoch seconds. We use relative time to avoid client/server time synchronization issues.
Retry-After
The number of seconds to wait until the rate limit window resets. Only sent when the rate limit is reached.
Internal Server Error. Error code 50001 indicates a failure in the backend data store.
