* Features:

  * Add Host field to TCPSocketAction ([#42902](https://github.com/kubernetes/kubernetes/pull/42902), [@louyihua](https://github.com/louyihua))

	* Add the ability to lock on ConfigMaps to support HA for self hosted components ([#42666](https://github.com/kubernetes/kubernetes/pull/42666), [@timothysc](https://github.com/timothysc))

    * inside of which a write lock was intended to prevent races against
    * VM creation, but the usage of the sync.RWMutex type is incorrect,
    * plus is placed in a defer call so the locking is effectively
    * nonexistent.  This patch adds an anonymous function call inside
    * the loop to correctly handle acquiring the write lock with deferred

- Kubernetes will try to acquire the iptables lock every 100 msec during 5 seconds instead of every second. This is especially useful for environments using kube-proxy in iptables mode with a high churn rate of services. ([#85771](https://github.com/kubernetes/kubernetes/pull/85771), [@aojea](http...

## Changelog since v1.14.9

### Other notable changes

* azure: update disk lock logic per vm during attach/detach to allow concurrent updates for different nodes. ([#85115](https://github.com/kubernetes/kubernetes/pull/85115), [@aramase](https://github.com/aramase))

   ([#121983](https://github.com/kubernetes/kubernetes/pull/121983), [@andyzhangx](https://github.com/andyzhangx))
- Client-go: Optimized leaders renewing leases by updating leader lock optimistically without getting the record from the API server first. Also, a new metric `leader_election_slowpath_total` was added to allow users to monitor how many leader elections are updated non-optimistically.

* Fixed scanning of failed iSCSI targets. ([#74306](https://github.com/kubernetes/kubernetes/pull/74306), [@jsafrane](https://github.com/jsafrane))
* fix detach azure disk back off issue which has too big lock in failure retry condition ([#76573](https://github.com/kubernetes/kubernetes/pull/76573), [@andyzhangx](https://github.com/andyzhangx))
