haproxy: use the master CLI for hot update

DEPLOY_HAPROXY_MASTER_CLI allows to use the HAProxy master CLI instead
of a stats socket for DEPLOY_HAPROXY_HOT_UPDATE="yes"

The syntax of the master CLI is slightly different, a prefix with the
process number need to be added before any command.

This patch uses ${_cmdpfx} in front of every socat commands which is
filled when the master CLI is used.
