XD-1983 NodeExistException on ModuleMetadata write

- Ignore ZK `NodeExistsException` on writing module metadata as this
is likely to happen when the container disconnects and reconnects
but the admin leader was not available to handle the container
departure event.
  - In this case, upon container disconnect the modules on that
container get undeployed and when the container reconnects
the `DeploymentListener` makes sure to deploy the same modules
except the fact that the ZK paths for the deployment and module
metadata already exists.

2nd commit message:

Fix code review comment

- Make sure to update the status even when `NodeExistsException`
is thrown while writing module metadata path.

Support SSL for RabbitMQ

Follow the RabbitMQ instructions to set up SSL for rabbitmq:

https://www.rabbitmq.com/ssl.html

In application.yml, servers.yml etc...

Property `useSSL` for simple SSL (no certificate validation).

Property `sslProperties' points to a protected properties file with secrets...

````
$ cat /secret/sslprops
keyStore=file:/secret/client/keycert.p12
trustStore=file:/secret/trustStore
keyStore.passPhrase=secret
trustStore.passPhrase=secret
````

servers.yml:

````
spring:
  rabbitmq:
   addresses: 10.0.0.3:5671
   username: guest
   password: guest
   virtual_host: /
   useSSL: true
   sslProperties: file:/secret/sslprops
