This commit is a breaking change: 1. `role` in DCS is written as "primary" instead of "master". 2. `role` in REST API responses is also written as "primary". 3. REST API no longer accepts role=master in requests (for example switchover/failover/restart endpoints). 4. `/metrics` REST API endpoint will no longer report `patroni_master`. 5. `patronictl` no longer accepts `--master` argument. 6. `no_master` option in declarative configuration of custom replica creation methods is no longer treated as a special option, please use `no_leader` instead. 7. `patroni_wale_restore` doesn't accept `--no_master` anymore. 8. `patroni_barman` doesn't accept `--role=master` anymore. 9. callback scripts will be executed with role=primary instead of role=master 10. On Kubernetes Patroni by default will set role label to primary. In case if you want to keep old behavior and avoid downtime or lengthy complex migrations you can configure `kubernetes.leader_label_value` and `kubernetes.standby_leader_label_value` to `master`. However, a few exceptions regarding master are still in place: 1. `GET /master` REST API endpoint will continue to work. 2. `master_start_timeout` and `master_stop_timeout` in global configuration are still accepted. 3. `master` tag is still preserved in Consul services in addition to `primary`. Rationale for these exceptions: DBA doesn't always 100% control the infrastructure and can't adjust the configuration.

|
We should check that patroni correctly responds to valid and not-valid API requests.
|
|
|
|
Scenario: check API requests on a stand-alone server
|
|
Given I start postgres0
|
|
And postgres0 is a leader after 10 seconds

|
|
And I receive a response state running
