v16.0.4: Cache Lock fix and Standard fixed

Fix for api.cache.lock

The old implementation of the api.cache.lock method did not check the result of the setnx function, which could have lead to multiple nodes acquiring the same lock multiple times.

Update to the latest version of Standard

The latest version of Standard.js checks for deprecated methods from node's core. We were using a few of these older methods and they have been removed.

Misc

• Update all dependent packages to their latest versions
