API discovery

To ease migration during major version upgrades, it is preferable to discover the API starting from an entry-point rather than to define all URIs.

Verbs do not change in major version upgrades but URIs might change.

The execution of a GET request on this URI returns a list of available functions.

GET https://[server]:[port]/[version]/api

Example: GET https://localhost:8082/7.2.1/api
