Remove get_crosslink_committees_at_slot and fix research/state_sim (#291)
* migrate attestation pool tests from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* rm obsolete, unused get_crosslink_committees_at_slot_cached(...) and migrate tests/test_state_transition from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* migrate tests/testutil from get_crosslink_committees_at_slot(...) to get_crosslink_committee(...)

* use more pervasive caching infrastructure, initially of compute_committee; remove buggy (and per-index) shuffling to fix research/state_sim, which was noticing validators on multiple shard committees; rm now-unused specific get_attesting_balance_cached

* add some get_active_validator_index caching

* rm obsolete/unused get_attesting_indices_cached

* rm get_crosslink_committees_at_slot(...)

* some more 0.7 changes -- some of which can't be completed pending some data structure updates -- and shard handling changes to offset with epoch start shards

With these changes, running a simulation is very close to running
an actual testnet. Some checks have been added in the client to
make sure you are not connecting to an incompatible network (e.g.
a network running with a different number of shards).

Zahary Karadjov 8f9a5441f1 More reliable network simulation
You'll need the latest versions of nim-eth-p2p, nim-serialization
and nim-json-serialization.

Before starting the simulation script, make sure to delete any previous
json files from the simulation folder:

```
rm tests/simulation/*.json
tests/simulation/start.sh
```

This should survive the creation of few blocks before diying with a
block validation error.
