SE-25: add testcase for dynamic resolve of proxy module, test for proxy_pass use domain name directly, and use upstream pool
	when use upstream pool, we test the loadbalance algorithm include:
    1) round_robin
    2) least_conn
    3) fastest
    4) ip_hash

SE-25: add dynamic resolve function for proxy module, this function can be enable by proxy_pass by use domain name directly, or by use upstream poo
    when use upstream pool, we support the loadbalance algorithm include:
    1) round_robin
    2) least_conn
    3) fastest
    4) ip_hash

if you want use dynamic resolve in a loadbalance algorithm besides above, you must modify the algorithm
