Strings get sent to the worker where booleans should

[taylordowns2000]

Building on #1513, I'm seeing that all values (including booleans) are being saved to the DB as strings. When they get passed to the worker, they no longer match the required JSON schema specification and we're probably going to run into a bunch of issues with this down the line.

Put simply, we're sending

{"requireSsl": "true"}

to the worker while the schema requires that we send

{"requireSsl": true}

Please check all types that we handle in the config schema and ensure that they're sent to the worker properly.
