Add deploy_on_init feature in full-set environment

[cliffano]

Deploy on initialisation feature has been introduced for Consolidated architecture. The same thing needs to be applied to Full-Set architecture.

Note: author-dispatcher and publish-dispatcher components will always deploy on initialisation by default due to dispatcher config files not having mandated structure (nothing stopping users from setting conf.d under /opt/my/company/name if they want to) hence the platform can't extract those config files.

As for author and publish components, it only makes sense for deploy on initialisation on a vanilla environment. Otherwise, in a non-vanilla (blue green deployment) scenario, the pre-defined snapshot already contains the repository.
