Jim Harris 6bef902ca5 rpc: add default UNIX domain socket listen address
RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.

-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.

Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option.  This keeps backward compatibility
for this release for anyone using the configuration file
still.

Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases.  We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.
