Allow to use same types in a range field as search query

[yansavitski]

Context: for the range type we have our condition that uses Date.parse and restricted by this function.

We want to give the user more control of the format for their data, so they can define their format in the search index and use that format in a range field. To achieve this we want to allow passing the same types as search query has, which allows to use dateMath in a range and any format for the date.
