Details pages generate api calls with group_by[date] instead of group_by[tag:tag_key]  for tag breakdowns, leading to "Page temporarily unavailable" error.

Steps to reproduce:

ci/ci beta env, cost-demo user

1. go to Openshift details page (the same issue is in all details pages)
2. group by: Tag
3. choose "environment" key
4. click to "prod" link

You will get "This page is temporarily unavailable"

api calls:

/api/cost-management/v1/reports/openshift/compute/?filter[time_scope_units]=month&filter[time_scope_value]=-1&filter[resolution]=monthly&group_by[date]=prod

/api/cost-management/v1/reports/openshift/memory/?filter[time_scope_units]=month&filter[time_scope_value]=-1&filter[resolution]=monthly&group_by[date]=prod

/api/cost-management/v1/reports/openshift/costs/?filter[resolution]=monthly&filter[time_scope_units]=month&filter[time_scope_value]=-1&group_by[date]=prod
