It should be "rabbit://openstack:pwd%23morepwd@controller"

'#' should be escaped.

Title:
  password with hash sign in URL in nova.conf crashes /usr/lib/python2.7
  /dist-packages/oslo_messaging/transport.py

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description:
  - Following https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html at step "Install and configure components: 3" running "su -s /bin/sh -c "nova-manage api_db sync" nova" crashes in /usr/lib/python2.7/dist-packages/oslo_messaging/transport.py if a URL in nova.conf contains a password with the hash sign (#). 

  Steps to reproduce:
  - follow https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html using e.g. a password of pwd#morepwd for RabbitMQ, i.e. in nova.conf: transport_url=rabbit://openstack:pwd#morepwd@controller
  - at step "Install and configure components: 3" run "su -s /bin/sh -c "nova-manage api_db sync" nova" as instructed

  Expected result:
  - url should be parsed resulting use user "openstack" with password "pwd#morepwd" and server "controller"

  Actual result:
  - parsing will fail with crash of /usr/lib/python2.7/dist-packages/oslo_messaging/transport.py parse function as url string content after "rabbit://openstack:pwd" is interpreted as fragment "morepwd@controller"

  Environment:
  - as resulting from following https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html with Ubuntu 16.04.
