in the job_classification.conf if there's a misconfigured site_bucket_criteria_expr you don't find it until runtime

[StevenCTimm]

If there is a malformed site_bucket_criteria_expr
(jsonnet is well formed but the stuff within the double quotes is not good pandas)

then you won't find out until the glidein_requests transform tries to execute it and errors out with a run time error.

Need some way to know if we have good Pandas query language in the config file.

Can't necessarily determine that all the variables we are querying on, exist, but should be able
to check if it's syntactically correct.

The incident in question had an extra single quote at the front of the string.
