Hi,

I would like to nominate myself to be the Watcher PTL for the Train cycle.

I began to contribute to Watcher project since 2016, and as a core reviewer
from Pike cycle.

In Stein, We have done a good job. We refactor the function of updating
the data model based Nova notifications, and add API Microversions for
Watcher. We also improve the unit tests and functional tests.

For the next cycle, there are some works we need to take into account:

* Supoort CERN's use cases.
* Add API to show the Watcher data model.
* Add support for the Placement Client.
* continue to improve the functional tests.

I have working with Watcher for several cycles, and I have a deep understanding
about Watcher. I'm happy to welcome new contributors on the project and ready
to answer any question on our channel #openstack-watcher.

Best Regards,
Canwei Li (licanwei)
