Move create config functions out of the main delta-processor.ts file. Change some any types to more specific types. Define document structure better. Move prometheus logic out of processor class. Do not call logger directly, listen for events and log them. Change logger to more PSR-3 compliant style. Extract amqp connection into its own class. Create avro and mongo objects in factory.
Configurable via the `pidfile' config option.
* bin/server.js: Accept `pidfile' config. Include path in greeting.
(writePidFile): Write to `pidfile' and unlink after exit.
* conf/vanilla-server.json (pidfile): Add configuration key.
This isn't ideal, but will allow using daemons classes from anywhere
on disk.
* bin/server.js: Interpret daemon path as relative to conf file path.
* conf/vanilla-server.json: Use relative path to `DevDaemon'.
This is based (very) loosely on an internal script to start the
daemon. It accepts a configuration and starts the daemon.
To accommodate the configuration, a number of miscellaneous changes
have been made.
The vanilla configuration shows the concept, but it has not yet been
fully implemented; that'll likely happen at a later date. Until then,
the existing environment-variable-based configuration will be used.
* bin/server.js: Add file.
* conf/vanilla-server.json: Example configuration added.
* src/server/daemon/Daemon.js (_httpPort): Remove field.
(_conf): Add field.
(__construct): [BC BREAK] Accept conf instead of port and log
priority. Move initialization code into `start'.
(start): [BC BREAK] Initialization code moved here. Now returns
promise for entire daemon, which will error in the event of an
error starting. Move existing code into `_startDaemon'.
(_startDaemon): Old `start' code. Invoked after `start'
initialization.
(_createDebugLog, _createAccessLog): Use configuration. Return
promise.
(_initHttpServer): Use configuration.
(_httpError): Add function to output error and exit. Extracted from
`_initHttpServer'.
* src/server/daemon/scripts.js: [BC BREAK] Append "program/" to
`LV_LEGACY_PATH' so that it can be re-used for script lookups
rather than using the cwd. This removes the need of the cwd being
the legacy src path.
