Create QC Checks for Data Relay Server Data Ingestion

[summer-mothwood]

As noted in #423 and based on findings in #453 , we suggest adding QC checks to the data relay server to alert the team of potential failures in the data pipeline. Some suggestions from the initial analysis include:

• build an alert when a given district has any missing days in the S3 bucket
• build an alert in Snowflake or dbt when the number of observations for a given station ID and/or district is lower than an expected threshold
• build a model to check data relay data against clearinghouse data (this is a temporary fix meant to alert of us new data issue patterns that may arise, and act as a secondary validation check until we turn the clearinghouse data collection off)
