cleanup: rename use_proxy_always to always_use_proxy to match cfg

This renames all occurences of use_proxy_always to always_use_proxy
to keep it inline with config values. This was a bit confusing.

Only significant change is that the payload in the plugins init
requests also contained the old name. No plugin currently seems to make
use of this variable yet. The old name 'use_proxy_always' is added when
deprecated APIs is enabled.

Changelog-Deprecated: Plugins: Renames plugin init 'use_proxy_always' to 'always_use_proxy'
