docs: Clarify configuration options apply to agent

Recently there have been a handful of GitHub issues and Discuss posts
where users have expected the `consul` CLI to make use of config
options defined in the agent configuration files, and are confused
when it does not honor those config options.

This change clarifies that command-line and configuration file options
documented on the /agent/options page only apply to the Consul agent,
instead of the Consul CLI.
