Add partition and macros support at raw sql mode

[LiorRacer]

What this PR does / why we need it:
Support for partition table and macros for raw sql
An example:

SELECT sum(int64_field_0) as metric, TIMESTAMP(date_field_1) as time
FROM `projectId.Lior.movies`
WHERE $__timeFilter(date_field_1) 
group by date_field_1
LIMIT 1000

Will translate to

SELECT sum(int64_field_0) as metric, TIMESTAMP(date_field_1) as time
FROM `projectId.Lior.movies`
where _PARTITIONTIME >= '2020-03-31 21:00:00' AND _PARTITIONTIME < '2020-05-26 20:59:59' AND  `date_field_1` BETWEEN '2020-03-31' AND '2020-05-26' 
group by date_field_1
LIMIT 1000
