[PATCH 0/6] Introduce replica local spaces

[Vladimir Davydov]

This patch introduces a new space option, is_local, which if specified
on space creation will render all changes done locally to the space
invisible to other replicas (see #3443). This is required for making
garbage collection state persistent (see #3442). For implementation
details, see patch 6.
