When we use queries combining group_by[cluster], start_date and end_date params with monthly resolution, the data section of OCP compute/volume/memory reports shows incorrect capacity. It seems like it shows the capacity for a single day only instead of the whole month.

Note that the value for the total capacity (in metadata section) seems to be correct.

Steps to reproduce:

• ingest OCP multi sources data
• see the ocp compute report for current month generated using time scope params and group_by cluster:
  /v1/reports/openshift/compute/?filter[resolution]=monthly&filter[time_scope_value]=-1&filter[time_scope_units]=month&group_by[cluster]=*

the capacity of the test_cost_ocp_delta cluster is 712.0 Core-Hours

• generate the ocp compute report using monthly resolution, start_date/end_date params and group_by[cluster]:
  /v1/reports/openshift/compute/?filter[resolution]=monthly&group_by[cluster]=*&start_date=2021-11-01&end_date=2021-12-08

                        {
                            "date": "2021-12",

the capacity of the test_cost_ocp_delta cluster is  96.0 Core-Hours
