MINOR: stats: indicate the number of servers in a backend's status
When dumping the stats page (or the CSV output), when many states are
mixed, it's hard to figure the number of up servers. But when showing
only the "up" servers or hiding the "maint" servers, there's no way to
know how many servers are configured, which is problematic when trying
to update server-templates.
What this patch does, for dumps in "up" or "no-maint" modes, is to add
after the backend's "UP" or "DOWN" state "(%d/%d)" indicating the number
of servers seen as UP to the total number of servers in the backend. As
such, seeing "UP (33/39)" immediately tells that there are 6 servers that
are not listed when using "up", or will let the client figure how many
servers are left once deducted the number of non-maintenance ones. It's
not done on default dumps so as not to disturb existing tools, which
already have all the information they need in the dump.
