James E. Blair 1b1eab77b0 Fix unknown label in metastatic driver
If a label is removed from the configuration while a node still
exists, the periodic cleanup performed by the metastatic driver
will raise an AttributeError exception when trying to access
the grace_time attribute, since the label pointer is None.

To address this, treat a missing label as if it has a grace time
of zero seconds.

This adds a test which simulates the issue.

This also adds an extra log entry for when a metastatic backing
node slot is deallocated is added so that we log both the allocation
and deallocation.

Nodepool

Nodepool is a system for managing test node resources. It supports launching single-use test nodes from cloud providers as well as managing access to pre-defined pre-existing nodes. Nodepool is part of a suite of tools that form a comprehensive test system, including Zuul.

The latest documentation for Nodepool is published at: https://zuul-ci.org/docs/nodepool/

The latest documentation for Zuul is published at: https://zuul-ci.org/docs/zuul/

zuul-announce

A low-traffic announcement-only list to which every Zuul operator or power-user should subscribe.

zuul-discuss

General discussion about Zuul, including questions about how to use it, and future development.

You will also find Zuul developers in the #zuul channel on Freenode IRC.
