Current Foreman ships a bundled websockify implementation. cdd8424fb4d31b390531cc1a1d74fb3820bae31a suggests it was updated to 1.6.1 but https://github.com/novnc/websockify/releases suggests the newest version is 0.9.0.

Foreman should depend on this and use an installed version from $PATH.

https://community.theforeman.org/t/consolidating-the-console/11215 also spoke about a bigger refactor which can be related, but unbundling might make that easier to achieve.
