Implement MIME parsing

This commit adds two core features to bmcweb:

1. A multipart mime parser that can read multipart form requests into
bmcweb.  This is implemented as a generic parser that identifies the
content-type strings and parses them into structures.

2. A /login route that can be logged into with a multipart form.  This
is to allow changing the login screen to a purely forms based
implementation, thus removing the very large whitelist we currently have
to maintain, and removing javascript from our threat envelope.

More testing is still needed, as this is a parser that exists outside of
the secured areas, but in this simple example, it seems to work well.

Tested: curl -vvvvv --insecure -X POST -F 'username=root' -F
'password=0penBmc' https://<bmc ip address>:18080/login

Returned; { "data": "User 'root' logged in", "message": "200 OK",
"status": "ok" }
