Bug in upstream when have quote

[lihz1990]

This is my test code, check_http_send is a directive of popular nginx module nginx_upstream_check_module

import nginx

UPSTREAM_BLOCK = """
upstream test0 {
    server 1.1.1.1:8080;
    check interval=3000 rise=2 fall=3 timeout=3000 type=http;
    check_http_send "GET /alive.html  HTTP/1.0\r\n\r\n";
    check_http_expect_alive http_2xx http_3xx;
}

upstream test1 {
    ip_hash;
    server 2.2.2.2:9000;
    check_http_send 'GET /alive.html  HTTP/1.0\r\n\r\n';
}
"""

data = nginx.loads(UPSTREAM_BLOCK)
print nginx.dumps(data)

and I got this output:

upstream test0 {
    server 1.1.1.1:8080;
    check interval=3000 rise=2 fall=3 timeout=3000 type=http;
    check_http_send GET /alive.html HTTP/1.0

;
    check_http_expect_alive http_2xx http_3xx;
}

upstream test1 {
    None;
}

There are 2 bugs here:

• Lost double quote in check_http_send line of upstream test0 .
• The upstream tets1 is freaky.

This is a awesome project. It will be glade to see you fix this.
