* /api/v1/weights endpoints * high resolution anomaly rate in parallel with queries; points and options in /api/v1/weights reflect the truth * context printing * merged metric_correlations with weights API; added parameter tier to select the tier to run the query; weight api now returns points per tier; added swagger info about weights api * moved metric_correlations files to web/api/queries as weights * added contexts filtering; renamed correlated_dimensions; weights API is always enabled; code cleanup * allow returning zero results
