Issue #956: Disable SQLAlchemy echo in MDR API (env-driven)

[dereck-symmetry]

Include:

• This is a fix for Issue MDR API SQLAlchemy engine uses echo=True — logs every SQL statement to CloudWatch #956. The default behavior for SQLAlchemy going forward will be for the echo to be set to "False". However, it is possible to turn the echo to True if that would be preferred in development environments.
