Support Anomalies for ClickHouse

[oleg-savko]

If understand current anomalies not support for clickhouse and simple tests end with following errors:

14:11:53  1 of 1 ERROR elementary_volume_anomalies_inflow_medium__hour__1__date_requested  [ERROR in 0.31s]

14:11:56  Done. PASS=2 WARN=0 ERROR=1 SKIP=0 TOTAL=3

when try to dive in code find following:

# Anomalies currently not supported on ClickHouse
@pytest.mark.skip_targets(["clickhouse"])
def test_anomalyless_table_volume_anomalies(test_id: str, dbt_project: DbtProject):
....

Does it in plan to add support for clickhouse?
or maybe something missed, and have workarounds for this?
