Subject: [PATCH] config: Add enable-authfile option

This option enables (or disables) usage of authfile. Can be 'yes' or 'no'.
Default is 'no'.

Booth usage of authfile was broken for long time (since commit
da79b8ba28ad4837a0fee13e5f8fb6f89fe0e24c).

Pcs was adding authfile by default, but it was not used. Once booth bug
was fixed problem appears because mixed clusters (with fixed version and
without fixed one) stops working.

This non-upstream option is added and used to allow use of
authfile without breaking compatibility for clusters
consisting of mixed versions (usually happens before all nodes are
updated) of booth (user have to explicitly
enable usage of authfile).

This patch is transitional and will be removed in future major version of
distribution.
