MagnetoDB is not handling SSL termination proxies

[Charles Wang]

If MagnetoDB API node is behind SSL termination proxy, the original protocol https and port number will be translated to http and port 8480 by ssl proxy. Therefor all urls/links will be wrong in MagnetoDB. This includes links/href in:
- CreateTable
- DescribeTable
- DeleteTable
- ListTables

The href values in the above API calls' responses can not be used by API user, and they expose internal protocol and port number.

For example, ListTables:
GET https://{{HOST}}/v1/{{PROJECT_ID}}/data/tables

Response:
...
"links": [
{
"href": "http://localhost:8480/v1/data/default_tenant/tables/Thread",
"rel": "self"
},
{
"href": "http://localhost:8480/v1/data/default_tenant/tables/Thread",
"rel": "bookmark"
}
],
...

    Handle URL rewriting of protocol port and host

    Added middleware UrlRewriterMiddleware to handle url rewriting because
    of SSL termination proxy.

    Two ways can be used depending on the deployment requirements:
    1. use configured values for protocol/port/host to override original
    values
    2. use HTTP headers injected by SSL proxy
