Adjust vm latests values to be second to last day

[myersCody]

Jira Ticket

COST-20

Description

This change will change the latest value to be the second to last day. The last day will always be partial data skewing the cpu and memory request amounts. So, we decided the best approach would be to switch the values to the second to last day.

Testing

1. Load data and hit the endpoint:

                            "request": {
                                "cpu": {
                                    "value": 1.0,
                                    "units": "Core"
                                },
                                "memory": {
                                    "value": 2.0,
                                    "units": "GiB"
                                }
                            }
