Alerts best practices

jsonnet: Drop cAdvisor metrics without (pod, namespace) label pairs.

jsonnet: Drop cAdvisor metrics with no (pod, namespace) labels while preserving ability to monitor system services resource usage

The following provides a description and cardinality estimation based on the tests in a local cluster:

container_blkio_device_usage_total - useful for containers, but not for system services (nodes*disks*services*operations*2)
container_fs_.*                    - add filesystem read/write data (nodes*disks*services*4)
container_file_descriptors         - file descriptors limits and global numbers are exposed via (nodes*services)
container_threads_max              - max number of threads in cgroup. Usually for system services it is not limited (nodes*services)
container_threads                  - used threads in cgroup. Usually not important for system services (nodes*services)
container_sockets                  - used sockets in cgroup. Usually not important for system services (nodes*services)
container_start_time_seconds       - container start. Possibly not needed for system services (nodes*services)
container_last_seen                - Not needed as system services are always running (nodes*services)
container_spec_.*                  - Everything related to cgroup specification and thus static data (nodes*services*5)

Previously, prometheus-adapter configuration wasn't taking into account
the scrape interval of kubelet, node-exporter and windows-exporter
leading to getting non fresh results, and even negative results from the
CPU queries when the irate() function was extrapolating data.
To fix that, we want to set the interval used in the irate() function in
the CPU queries to 4x scrape interval in order to extrapolate data
between the last two scrapes. This will improve the freshness of the cpu
usage exposed and prevent incorrect extrapolations.
