In the agent token mechanism, restrictions exist when a an agent token can be generated, and unfortunately this has to be done on the conductor side involving a lock and a task because we need to save the state of the node. As such, we were in a situation where we were waiting on DB node locking, which would prevent the agent from getting a node, and potentially causing the lookup operation to fail, eventually. We now quickly return NodeLocked which shouldn't cause the agent any issues, although we need to improve error handling there as well. Change-Id: Ice335eed82b936753be99eedb16ceccf8a9a86a8

Team and repository tags
Overview
Ironic consists of an API and plug-ins for managing and provisioning physical machines in a security-aware and fault-tolerant manner. It can be used with nova as a hypervisor driver, or standalone service using bifrost. By default, it will use PXE and IPMI to interact with bare metal machines. Ironic also supports vendor-specific plug-ins which may implement additional functionality.
