Changes in field names

Field names for container and host metadata changed. In case a changed field was used in dashboards or alerts, the renaming could break existing dashboards or alert rules in Sematext Cloud.

Original Field Name New Field Name
host os.host
ip os.host_ip
container_id container.id
image container.image
container_name container.name
kubernetes.podName kubernetes.pod.name
kubernetes.containerName kubernetes.pod.container.name
kubernetes.containerid kubernetes.pod.container.id
- kubernetes.pod.container.host.hostname

The change was required to correlate container metrics and logs by those fieds.
