Release v1.1.10

Rancher Kubernetes Engine (RKE) is a CNCF-certified Kubernetes distribution that runs entirely within Docker containers. It works on bare-metal and virtualized servers. With RKE, the installation and operation of Kubernetes is both simplified and easily automated, and it’s entirely independent of the operating system and platform you’re running.

1. CVE-2020-8564 - Docker config secrets leaked when file is malformed and log level >= 4
2. CVE-2020-8566 - Mask Ceph RBD adminSecrets in logs when logLevel >= 4
