Fix long standing bug with pcp_node_info.
It appears that occasionally pcp_node_info shows backend_status field
as "quarantine" when it should be "down". While pcp_node_info shows
the status, first it checks the backend_status member in BackendInfo
struct. If it is 3, then checks quarantine member. If it is other than
0, then the backend_status field is shown as "quarantine". So if
garbage remains in quarantine member, it is shown as "quarantine". The
BackendInfo struct is transferred from pcp_worker process to pcp
frontend client. Unfortunately when the quarantine member was added by
commit 54af632c, it was forgotten to modify pcp_worker.c and
pcp_frontend.c so that the "quarantine" member is transferred.
Fix is needed to be back patched to 3.7, when the "quarantine" member
was first added.
