* add GetCommandsFromPipeline
* refactor method GetCommandType to func GetExpressionCommandType
* add function to create fingerprint frames
* add function to determine whether raw query represents a hysteresis command and a function to patch it with loaded metrics
* extend threshold command with second evaluator called `unloadEvaluator`
* Introduce a new expression command Hysteresis and update Threshold unmarshaller to create the HysteresisCommand if the second eval
* add feature flag `recoveryThreshold`
* update unmarshal threshold command to not re-marshall because it breaks frame definition by shuffling the schema and data fields
Changes SSE to not always fail all queries when one fails. Now only the query itself, and nodes that depend on it will error.

Execute all queries to the same datasource in a single request.
Uses the query index and the graph node ID index, and then a stable dependency graph sort based on node input index number in attempt to keep the original query order intact.
* introduce a function checkIfSeriesNeedToBeFixed to scan all value fields in the response and provide a function that updates Series so they can be uniquely identifiable. Only Graphite and TestData are checked.
* update `convertDataFramesToResults` to run this function and provide it to WideToMany
* update WideToMany to run the fix function if it is not nil
* introduce a new node-type ML and implement a command outlier that uses ML plugin as a source of data.
* add feature flag mlExpressions that guards the feature
* add data source uid to QueryError
* add error and datasource uid to tracing
* split queryDataResponseToResults to two functions one to extract frame from the result, and another to convert it
* propagate logger with context to convertDataFramesToResults
* add NodeTypeFromDatasourceUID and DataSourceModelFromNodeType()
* deprecate expr.DataSourceModel
* replace usages of IsDataSource to NodeTypeFromDatasourceUID
* replace usages of DataSourceModel to DataSourceModelFromNodeType()
