Enable passing FAILPOINTS at startup.

Browse Source 
- Pass through FAILPOINTS environment variable to the pageserver in
  "neon_local pageserver start" command

- On startup, list any failpoints that were set with FAILPOINTS to the log

- Add optional "extra_env_vars" argument to the NeonPageserver.start()
  function in the python fixture, so that you can pass FAILPOINTS

None of the tests use this functionality yet; that comes in a separate
commit.
