The iteration order over maps is not specified and is not guaranteed
to be the same from one iteration to the next. If a map entry that
has not yet been reached is removed during iteration, the corresponding
iteration value will not be produced. If a map entry is created during
iteration, that entry may be produced during the iteration or may be skipped.
The choice may vary for each entry created and from one iteration to
the next. If the map is nil, the number of iterations is 0.

* Search: Fixes search limits and adds a page parameter

This adds a page parameter to search api without adding
any major breaking change.

It does at an api validation error when trying to use
a limit beyond 5000. This is a breaking change. We could
remove this and have it only in the docs and describe that this
is a limit that grafana will apply silently.
