Weak subjectivity start from genesis (#1675)
This commit was edited by Paul H when rebasing from master to
v0.3.0-staging.

Solution 2 proposed here: https://github.com/sigp/lighthouse/issues/1435#issuecomment-692317639

- Adds an optional `--wss-checkpoint` flag that takes a string `root:epoch`
- Verify that the given checkpoint exists in the chain, or that the the chain syncs through this checkpoint. If not, shutdown and prompt the user to purge state before restarting.
