dvc gc --all-commits --cloud: Inconsistency in behavior when using "config.local" file for "gc" and "push" commands.

Bug Report

Inconsistency in behavior when using "config.local" file for "gc" and "push" commands. I am using a password-based authentication system for a remote SSH system. The "url" field is in the regular config file, and the "password" field is in the "config.local" file.

When running "dvc push" commands, this successfully picks up the url from the regular config file, and the password from the config.local file. However, running "dvc gc" related commands fails, and throws an error related to a missing url field. However, if i copy-paste the url field from the regular config file into the config-local file, this will work.

Reproduce

---

config file:

[core]
    remote = localremote
['remote "localremote"']
    url = ssh://@DVCSystem:22/DVC/

---

config.local file:

['remote "localremote"']
    password = 12345678

---

1. Now run the dvc push command, and verify it is working.
2. Now run dvc gc --all-commits --cloud command, and it will fail.

Expected

An error will be thrown about a missing URL field in the dictionary.

I am aware that this issue can be solved by copy-pasting the URL from config file into the config.local file. But i'm hoping for a proper fix for this.
