Root document contains incorrect href with 0.0.0.0

[Pete Zaitcev]

If the default configuration is used, with bind_host=0.0.0.0, the root document looks like this:

{"versions": [{"status": "CURRENT", "id": "v1.1", "links": [{"href": "http://0.0.0.0:9292/v1/", "rel": "self"}]}, {"status": "SUPPORTED", "id": "v1.0", "links": [{"href": "http://0.0.0.0:9292/v1/", "rel": "self"}]}]}

These href values cannot be used by a remote client.

The correct way to reconstruct remote URLs require using the HTTP request header Host: for HTTP 1.1 clients, or the connect address for HTTP 1.0 clients. The bind address should not be used.

Note that using bind address is also incompatible with IPv6.

    Return correct href if bind_host is 0.0.0.0.

    The existing code returns incorrect href= in the root document (aka
    "version" document) if the default configuration is used. If a remote
    system accesses Glance API, the netspec of href= contains 0.0.0.0,
    which cannot be used for further remote accesses. This happens because
    attempts to use local configuration or the bind address to reconstruct
    URLs are futile.

    The correct way resolve this problem is to use the Host: header
    of the HTTP request. As a bonus, it works with IPv6, should we ever
    support it.
