Setup steps for all test cases.
Focus for these is to cover all API checks for ModelDataHandler.
Hence, this does all setup creating metric, waiting for
metricData across all testcases, all API call for querying metricData
will be against single metric created in setup
Setup Process
1) Update conf with aws credentials, ManagedTempRepository will not
work in this test
2) Select test instance such that its running from longer time,
We are using instance older than 15 days
3) Create Metric, wait for min metricData rows to become available
Set to 100, configurable
4) Pick testRowId, set it lower value this will make sure to have
Non NULL value for anomaly_score field for given row while invoking
GET with consitions, set to 5
5) Decide queryParams for anomalyScore, to and from timestamp
