DEPLOY_HAPROXY_HOT_UPDATE="yes" now allows to add a new certificate
within HAProxy instead of updating an existing one.
In order to work, the ${DEPLOY_HAPROXY_PEM_PATH} value must be used as a
parameter to the "crt" keyword in the haproxy configuration.
The patch uses the following commands over HAProxy stats socket:
- show ssl cert
- new ssl cert
- set ssl cert
- commit ssl cert
- add ssl crt-list
