Upstream keepalive: keepalive_requests directive.

The directive configures maximum number of requests allowed on
a connection kept in the cache.  Once a connection reaches the number
of requests configured, it is no longer saved to the cache.
The default is 100.

Much like keepalive_requests for client connections, this is mostly
a safeguard to make sure connections are closed periodically and the
memory allocated from the connection pool is freed.
