While doing research for this bugzilla[1] I found that since the
actual certificate PEM file is being bind mounted the mount is acting
as a hard link to the inode of the PEM rather than just a pointer to
it's location in the directory. When the new file is copied over the
inode is updated but the container still maintains a link to the stale
inode. This patch copies the contents of the certificate into the
container so that the HUP of HAProxy will reload the certificate.
