(#359) OAuth2 support [incubating]
Hermes supports Resource Owner Password Credential Grant scenario. It is possible to declare multiple OAuth providers in Hermes, along with their credentials. Each subscription can choose a provider and defines own user & password.
(#556) Added source and target hostname information to tracking

- on Frontend side:
hostname: hostname of Frontend host that received the messageremote_hostname: IP address of events producer (who published)
- on Consumers side:
hostname: hostname of Consumer host that was handling the messageremote_hostname: IP address/hostname of host that acknowledged/rejected message (who received)
(#561) Consumers process model improvements
Improving the stability of new internal Consumers process model by adding consumer process graceful shutdown and filtering unwatned signals (i.e. sequential START & STOP) which might cause instability.
For monitoring purposes two new metrics (counters) were created in Consumers that compare the assignments state vs the actual consumers running:
consumers-workload.monitor.missing.count- how many processes are missing compared to assigned amountconsumers-workload.monitor.oversubscribed.count- how many processes exist although they should not, as this instance of Consumers is not assigned to run them
In addition to metrics, warning logs are emitted with details about subscription names missing/oversubscribed.
