[cdc_stream] Switch asset_stream_manager to use Lyra (#25)

Switch asset_stream_manager to use Lyra

Lyra has a nice simple interface, but a few quirks that we work
around, mainly in the BaseCommand class:
- It does not support return values from running a command.
- It does not support return values from a custom arg parser.
- Lyra interprets --bad_arg as positional argument.

Fixes #15
