Reimplement marketstore and elasticsearch daemons

Using the new `._ahab.start_ahab_service()` mngr of course, and now
support user config overrides (such that our defaults can be modified by
a keen user, say using a config file, or for testing). This is where the
functionality moved out of the `pikerd` init has been moved - instead of
being triggered by bool flag inputs to that factory.

For marketstore actually support overriding the entire yaml config via
runtime `_yaml_config_str: str` formatting with any passed user dict,
primarily focussing on supporting override of the sockaddrs for testing.
