Mike Reeves 81c0f2b464 so-yaml.py: tolerate missing ancestors in removeKey
replace calls removeKey before addKey, so running `so-yaml.py replace`
on a new dotted key whose parent doesn't exist — e.g., postgres.auth
fanning postgres.telegraf.user into a minion pillar file that has
never carried any postgres.* keys — crashed with
    KeyError: 'postgres'
from removeKey recursing into a missing parent dict.

Make removeKey a no-op when an intermediate key is absent so that:
  - `remove` has the natural "remove if exists" semantics, and
  - `replace` works for brand-new nested keys.
