refactor(monitor): remove `kube_hpa` metrics
Background
Part of
gitlab-com/gl-infra/infrastructure#13973 is
upgrading kube-state-metrics
to v2.20
from v1.9.7
this introduces
a breaking
change
which renames the kube_hpa_
metrics to
kube_horizontalpodautoscaler_
.
Solution
!4017 (merged) added
support for kube_horizontalpodautoscaler_
metric, and
kube-state-metrics
was upgraded in gprd
in
gitlab-com/gl-infra/production#5805 (closed). The
kube_hpa_
metrics are no longer useable so remove them.
