Cleanup IssueBasic entity to keep it basic and move extra attributes
to Issue entity which contains more details

When issues_controller endpoint was used for search, the parameters
passed to the controller were slightly different then the ones
passed to API. Because the searchbar UI is reused in different
places and builds the parameters passed to request in same way
we need to account for old parameter names.


Add issues_statistics api endpoints

Adds issue_statistics api endpoints for issue lists and returns
counts of issues for all, closed and opened states.


Expose more label attributes based on a param

When requesting issues list through API expose more attributes
for labels, like color, description if with_labels_data param is
being passed, avoiding this way to change response schema for users
that already use API.

String#underscore isn't particularly slow, but it's possible for us to
call it many times in a users autocomplete request, with mostly-static
values ('User', 'Group', etc.). We can memoise this and save a
surprising amount of time (around 10% of the total request time in some
cases).
