Rename role haproxy to loadbalancer

For now role haproxy is maintaining haproxy
and keepalived. In follow-up changes there is also
proxysql added.

This patch is *only* renaming/moving stuff to more
prominent role loadbalancer, and moving also specific
templates to subdirectory.

This was done only to better diff in follow-up
changes.
