Fix health-monitors with ALPN members

Browse Source 
Using HTTP or HTTPS health-monitor on a ALPN pool failed with SSL
errors.
haproxy doc mentions that when using "check" with ALPN servers, the
check-alpn option must be enabled.

Fixed a bug with HTTP/HTTPS health-monitors on pools with ALPN protocols in
the amphora-driver. The healthchecks sent by haproxy were flagged as bad
requests by the backend servers. Updated haproxy configuration to use ALPN
for the heathchecks too.
