Replace date/datetime equals filter with a pair of greaterOrEqualThan and lessOrEqualThan

[Dergash]

Currently when user applies a filter to date/dateTime field it's an equals filter which is send to Tesler API endpoint and later split into two different search specifications on backend, replacing time part with beginning of the day and the end of the day.

It is required to have a range picker as a filter control instead and instead of equals filter send a pair of greaterOrEqualThan and lessOrEqualThan to Tesler API endpoint.
