Loki backend for rules check

[adyanth]

There was a backend flag to rules check that allowed passing in Loki as an option. Is there an alternative to it now?

https://github.com/grafana/cortex-tools/blob/1499f5fb286e672cd238a525169d4cb05f964eab/pkg/commands/rules.go#L51

I see this #7
Will this never be supported?

Hey @adyanth, I believe Loki is out of the scope of this tool now and they should have their own tool to perform such kind of task. Hence, I am going to close this issue
