The patch supports synchronization of Pod information
(Number of Pods, Pod name) between TackerDB and Kubernetes.
If there are differences in the Pod information,
it will synchronize the TackerDB information with the
Kubernetes information.
This process is performed periodically, and its interval
is configurable.
