Import Package Rename Policy
Package Maintainer Docs currently contain page "Package Rename Process",
which mainly contains normative policy statements.
Such rules should come from a FESCo policy.
It looks like that page was always intended to contain a FESCo policy,
and is simply currently stored in the wrong place.
Moving the policy to FESCo docs,
so that going forward, it can managed as a proper policy.
Grammar, formatting and links are slightly modified
to correct errors and match style of other FESCo policies.
The substance is not changed.
