Subject: Add --enable-rapi parameter to configure
X-Git-Tag: v1.2.4~64
X-Git-Url: https://code.grnet.gr/git/ganeti-local/commitdiff_plain/130440e7d0f26fb256b801c1474dccfe6f3cb76c

Add --enable-rapi parameter to configure

This allows developers and packagers to control whether they want to start
the remote API daemon, ganeti-rapi, automatically or not.
