Udf parameters should be automatically cast to double

[vpapavas]

Describe the bug
Udf parameters are interpreted as BigDecimals which causes existing udf to fail because they expect double.

To Reproduce
Steps to reproduce the behavior, include:

1. The version of KSQL.
   Current master
2. Sample source data.
   No data needed
3. Any SQL statements you ran
   Quickstart guide:

CREATE STREAM riderLocations (profileId VARCHAR, latitude DOUBLE, longitude DOUBLE) WITH (kafka_topic='locations', key='profileId', value_format='json', partitions=1);

SELECT * FROM riderLocations
WHERE GEO_DISTANCE(latitude, longitude, 37.4133, -122.1162) <= 5 EMIT CHANGES;

Actual behaviour
A clear and concise description of what actually happens, including:

1. CLI output
