Add plugin CLI argument (#6064)

Browse Source 
* Add plugin CLI argument

While working on supporting CustomValues in Plugins I stumbled upon the
test utilities defined in [nu-test-support][nu-test-support]
and thought these will come in handy, but they end up being outdated.
They haven't been used or since engine-q's was merged, so they are
currently using the old way engine-q handled plugins, where it would
just look into a specific folder for plugins and call them without
signatures or registration. While fixing that I realized that there is
currently no way to tell nushell to load and save signatures into a
specific path, and so those integration tests could end up potentially
conflicting with each other and with the local plugins the person
running them is using.

So this adds a new CLI argument to specify where to store and load
plugin signatures from

I am not super sure of the way I implemented this, mainly
I was a bit confused about the distinction between
[src/config_files.rs][src/config_files.rs] and
[crates/nu-cli/src/config_files.rs][crates/nu-cli/src/config_files.rs].
Should I be moving the plugin loading function from the `nu-cli` one to
the root one?

[nu-test-support]: 9d0be7d96f/crates/nu-test-support/src/macros.rs (L106)
[src/config_files.rs]: 9d0be7d96f/src/config_files.rs
[crates/nu-cli/src/config_files.rs]: 9d0be7d96f/crates/nu-cli/src/config_files.rs

* Gate new CLI option behind plugin feature

* Rename option to plugin-config
