Statefulset metadata label has invalid value (too long)

[mei-ling]

Describe the bug

The name in the label seems to tag on the remote name:

Warning FailedCreate 14m (x730 over 8d) statefulset-controller create Pod thanos-sausw2-perf-compute-remote-sausw2-perf-compute-rule-0 in StatefulSet thanos-sausw2-perf-compute-remote-sausw2-perf-compute-rule failed error: Pod "thanos-sausw2-perf-compute-remote-sausw2-perf-compute-rule-0" is invalid: metadata.labels: Invalid value: "thanos-sausw2-perf-compute-remote-sausw2-perf-compute-rule-768cbbd9b8": must be no more than 63 characters

this is making it too long. it seems like you're taking these 3 lines to form the name:

Labels:
app.kubernetes.io/managed-by=thanos-sausw2-perf-general
app.kubernetes.io/name=rule
monitoring.banzaicloud.io/storeendpoint=remote-sausw2-perf-general

Steps to reproduce the issue:

Normal Thanos Operator deployment

Expected behavior
no repeats on the name making it unnecessarily long. make the metadata label name generation more graceful.

Thank you we will review (and at least truncate long names)
