* node/approval-voting: test for invalid validator index in assignments

This commit adds a unit test to show that, currently, validator indexes
greater than n_validators (or the length of the approvals bitvector) are
counted in n_assignments. In the subsequent commit we will correct this
behavior.

* node/approval-voting: ignore invalid validator indexes in n_assignments

This commit ignores any validator assignments whose index is beyond
n_validators. Without this check, an improperly crafted assignment would
be counted towards the approval.

It still remains that n_assignments and count_no_shows inspect the
number of validators and approvals, respectively. Ideally we would
add greater safety around ensuring these two values cannot differ.

* node/approval-voting: extract and test count_no_shows method

This commit extracts no_show computation into a pure function so that it can be
extensively unit tested.

* node/approval-voting: ignore invalid validator indexes in count_no_show

Previously indexes that were past the length of the approvals bitvector
would contribute to the no_show count or the next_no_show value. This
commit changes the behavior to ignore garbage values.

* node/approval-voting: add comment for next_no_show adding clock_drift

* cleanup more tests and spaces

* Allow council to use scheduler

* westend doesnt have council

* extract determine_new_blocks into a separate utility

* rework docs

* node/approval_checking: break out filled_tranch_iterator method

In the subsequent commit, we will begin to test this method in
isolation.

* node/approval-voting: fix tranche back-filling algorithm

Previously, this algorithm would generate duplicate, empty entries for
tranches (1..pre_end). This is caused because the initial value (0) for
gap_end is treated as the end of a prior tranche that wasn't actually
processed. The first pass thus would add (1..tranche) empty entries, in
addition to the (0..pre_end) empty entries chained at the end of the
method.

This is fixed by using the current tranche as the gap_start for the
first iteration, ensuring that the approval_entries_filled only produces
entries in the range (pre_end..post_start).
