Allow parameters to be passed to headers through SQL in WHERE clause

Some APIs require parameters (e.g. digital signature) in the headers to be generated at access time.So I'm wondering if we can pass it in through filter statement.

Perhaps we could design it like the params field in connections parameter. For example:
 
Config:

{ "url": "https://api.sunrise-sunset.org/json", "requireTail": false, "params": ["body.lat", "body.lng", "body.date", "header.header1"], "parameterLocation": "json_body" }

 
SQL Query:
SELECT * FROM api.sunrise

WHERE `body.lat` = 36.7201600

AND `body.lng` = -4.4203400

AND `body.date` = '2019-10-02'

AND `header.header1` = 'value1';
 
Post body:

{ "lat": 36.7201600, "lng": -4.4203400, "date": "2019-10-02"}

 
Headers:

{ "header1": "value1", ……}
