While processing a sigv4 presigned url request, Bookshelf needs to
be able to determine whether the presigned url is valid, appropriately
signed, etc.

The only way I know to do this is to create a new presigned url
using whatever inputs the original presigned url was created with, and
compare the two presigned urls.  In order to do this, I have to use the
same host header and date the original presigned url was created with.
But it wasn't possible to pass in a host header and date, thus this commit.

1) Host headers are treated inconsistently between various componenents
(erlcloud, mini_s3, bookshelf, etc).

2) The generated host header was incorrect in certain cases, eg the host
header generated from http://127.0.0.1:4321 left off the port and resulted
in Host: 127.0.0.1.  However host header specs say that in the case of a
missing port the assumed port will be based on the scheme - 80 for http, 443
for https.  So the port should be added in this case, as it is 4321.

Some server configurations (uppercase letters in FQDNs) can cause
sigv4 signature calculations using uppercase letters in the 'value' of the
host header key-value pair (example: "host: Whatever" vs "host: whatever").
Bookshelf or S3 will then fail on signature verification because the
host header key must be in lowercase for sigv4.

Nginx was found to be one of the culprits causing the issue, but
changing the nginx configuration is opening more of a can of worms than
fixing the issue here.
