[API-Design] Custom major and minor time interval arrays 

Right now there is no endpoint to manipulate possible time intervals for major and minor ticks.
With this PR I introduce an API endpoint to provide custom time intervals.
To cover basic scenario I provide function, which easily can filter existed interval within some range. It might go directly to previously mentioned API, which will accept array or desired range.
? How is this different from the time formatter?  May want to change the names of both formatters as appropriate
