Fix Stack Monitoring with custom certificate without CA (elastic#5310) (

elastic#5319)

Stack Monitoring incorrectly assumed that if the monitored Elastic resource has TLS enabled, there is a CA to configure in the input section of the Metricbeat config. This overlooked that you can have a certificate issued by a well-known CA, so you don't always provide a CA when TLS is enabled. This is fixed by differentiating between isSSL/isTLS and HasCA.

[1.9] Stop using deprecated xpack.monitoring.* settings (elastic#5136) (

elastic#5137)

Completely remove the `xpack.monitoring.*` settings as they were never needed for stack monitoring.

Fix Agent volumes when an association has no CA (elastic#4833) (elast…

…ic#4834)

This commit fixes an issue that occurs if you associate an Agent with a Kibana without TLS. In this case, the association Agent<->Kibana does not have a CA and this breaks the volumeMounts of the Agent container because we returned instead of continuing to populate the slice of volumes.
