This fixes <https://tickets.puppetlabs.com/browse/MODULES-1741>.

HAProxy's `bind` parameter for listen and frontend services accepts
multiple ways of specifying addresses, ports, port ranges, sockets and
bind options. The template `templates/fragments/_bind.erb` that
processes the `haproxy::listen::bind` and `haproxy::frontend::bind` hash
should accomodate that, meaning specifically that it should not assume
that a valid bind configuration is universally of the format
`bind <ip address>:<port> [<options>*]`. The HAProxy documentation at
http://cbonte.github.io/haproxy-dconv/configuration-1.5.html#4.2-bind
details how complex the `bind` configuration can be.

The `templates/fragments/_bind.erb` template now processes the `bind`
hash very simply by using the hash keys as "address and/or port" and the
key's value as a list of bind options that together make up a single
`bind` line in the resulting listen or frontend service configuration.

Most notably there is no more IP address or port validation. The values
are taken as is from the `bind` hash. The rationale behind that is
discussed in <https://tickets.puppetlabs.com/browse/MODULES-1741>.

Contains updated and expanded documentation, and updated spec tests.
