Drop requirement to provide marquez.yml for seed cmd

[wslulciuc]

Problem

The marquez.yml arg is not used in the seed cmd.

Solution

Use io.dropwizard.cli.Command instead of io.dropwizard.cli.ConfiguredCommand to no longer require passing marquez.yml as an arg to the seed cmd:

java -jar marquez-api.jar seed --help
usage: java -jar marquez-api.jar
       seed [--url URL] --metadata METADATA [-h]

seeds the HTTP API server with metadata

named arguments:
  --url URL              the HTTP API server url (default: http://localhost:8080)
  --metadata METADATA    the path to the metadata file (ex: path/to/metadata.json)
  -h, --help             show this help message and exit
