 Description   

Description

Downstream Change Summary

The "touch" command was removed from the codebase.

Description of Linked Ticket

The "touch" command is supposed to pull all data into cache. Only MMAP supported "touch". See docs.

The "inMemory" and "ephemeralForTest" storage engines do support the command, but they just return "OK" as a no-op. All other storage engines, including WiredTiger, return an error, so there's no need to deprecate the command first.

The functionality of "touch" can be implemented by "warming up" the cache with collection and index scans.

Scope of changes

The docs were removed in 4.2 version as well as mentioned in 4.2 rel notes and compatibility page.
Will just use this to add the redirect as that was forgotten.

Impact to Other Docs
