Conan CLI: Add option to conan remove to just skip without error if package does not exist about conan HOT 2 OPEN

Hi @vincesp

This doesn't look like a docs issue, but a client one. Moving it to the Conan client repo.

from conan.

The conan remove command is missing an option to skip without returning an error if the package to be removed does not exist.

$ conan remove zlib/1.4
Remove summary:
Local Cache

This works without failing, not sure what you mean (zlib/1.4 doesn't exist yet)

Background: It is really cumbersome to build an Azure pipeline that detects if a package exists and only runs the conan remove task if it does. If using a pool with numerous agents, we cannot be sure in which state the conan cache on every single agent is, so we need to clean the cache just to be sure.

It is not clear the background. Why would you remove a package if it exists? The whole purpose of using Conan is not having to rebuild something that already exists, this flow shouldn't be necessary in the first place.
