Winson Chan e003849ecf Engine as a standalone process 
Refactored engine to run as a standalone process. The engine is
modified to use the RPC client/server design pattern from
oslo.messaging. A new launch option is included to run the
engine separately. The API server communicates with the engine
via the RPC client. A pecan hook is used to pass a common client
instance with appropriate transport configuration to the API.

Mistral

Task Orchestration and Scheduling service for OpenStack cloud

Running in development mode

### Installation First of all, in a shell run:

tox

This will install necessary virtual environments and run all the project tests. Installing virtual environments may take significant time (~10-15 mins).

### Running Mistral API server To run Mistral API server perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server api --config-file path_to_config

Note that an example configuration file can be found in etc/mistral.conf.example.

### Running Mistral Engines To run Mistral Engine perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server engine --config-file path_to_config

### Running Mistral Task Executors To run Mistral Task Executor instance perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server executor --config-file path_to_config

Note that at least one Engine instance and one Executor instance should be running so that workflow tasks are processed by Mistral.

### Debugging To debug using a local engine and executor without dependencies such as RabbitMQ, create etc/mistral.conf with the following settings:

[DEFAULT]
rpc_backend = fake

[pecan]
auth_enable = False

and run in pdb, PyDev or PyCharm:

mistral/cmd/launch.py --server all --config-file etc/mistral.conf --use-debugger
