Make pagination optional for issuables

Check MR state before submitting queries for discussion state

Closes #42236

See merge request gitlab-org/gitlab-ce!16788

It appears that some legacy diff notes on GitLab.com have invalid line codes,
which means truncated_diff_lines won't work. This is just a band-aid solution,
as neither the diff nor the discussion will display correctly for these notes,
but they won't cause a 500 error.

Port changes from gitlab-org/gitlab-ee!4064 to CE

See merge request gitlab-org/gitlab-ce!16796

On epics roadmap page we list all epics in the given time frame
without pagination (at least for the first iteration), in this
case it would be nice to use the existing issuables index logic
except pagination (see MR gitlab-ee!4281). For this reason this
patch allows to easily disable pagination.
