Subject: Repository setup: Warn about unknown keys

Warn if a repository definition contains unknown keys (that
are therefore ignored), as this often indicates a typo in the
repository specification. However, for some common naming of
extensions (currently: "bootstrap") keep the warning at a level
below the default for reporting.
