Improvements to exception handling in the Cisco plugins. Changes
include:
- Added mapping of Cisco exceptions to HTTP codes
(extension to FAULT_MAP).
- Removed several unused Cisco exception definitions.
- Added several new Cisco exceptions for fault conditions.
- Added several rollbacks for various sequential operations, e.g.:
* Create port: Nexus sub-plugin fails after OVS sub-plugin success
* Create port: Nexus switch conig fails after adding binding to
Nexus binding database
* Delete port: OVS sub-plugin fails after Nexus sub-plugin success
- Delete Port: Reversed order of OVS/Nexus sub-plugin calls so that
it is done in the reverse order as is done for create port.
- Removed several empty except/raise blocks
- Delete network: Removed call to Nexus sub-plugin delete_network,
since that is a no-op.
- Removed a block of unused code in model's create_network method.
- Added several unit testcases, including patching of OVS, Cisco
and Nexus config.
- Remove CISCO_TEST configuration from cisco plugin
config .ini file.
