fuel should not parse password vCenter from UI

Looks related to this: http://docs.openstack.org/developer/oslo.config/cfg.html#option-value-interpolation. The solution is to escape these values.

Fuel project entered Soft code freeze state, it means that only Critical and High bugs are primary targets, Medium
bugs are not fixed.

Two options to workaround this problem:
- change password for account that will be used by nova-compute to operate vCenter
- edit nova-compute configuration file and change all occurencies of $ with $$ and restart nova-compute service

Updating priority to High for customer-found issues, so they don't get moved to 7.0. Let's address this in 6.1

Escalating priority to Critical, becase deployment process fails. Nova-compute service fails to start:

Fix proposed to branch: master
Review: https://review.openstack.org/178699

Easy workaround for this problem:
Type $ as $$ in vCenter password, this way deployment process goes fine.

    Replace all occurrences of $ with $$ in vCenter input values

    - OpenStack services may reference to previously defined variable in
      configuration files using $ (dollar sign), e.g. 'metadata_host =
      $my_ip'. Interpolation can be avoided by using $$. Passwords often
      contain metachars and $ is one of them. We must replace all $
      occurrences with $$, otherwise service will fail to start because it
      cannot interpolate non-existing variable.
    - add static method escape_dollar() to VMwareDeploymentSerializerMixin
      class that implements conversion
    - also handle username and regular expression that is used for datastore
      search
    - provide input values with '$' in test fixture vmware_attributes.json
    - modify integration test

Verified at Fuel ISO#392
OS Ubuntu, Centos

Steps to reproduce:
1. Create env with 1 controller node.
2.Change vsphera password to ''$Qwer!1234$"" and set new vsphera password on env
3. Deploy env

Change abandoned by Andriy Popovych (<email address hidden>) on branch: stable/6.0
Review: https://review.openstack.org/182420
Reason: new change https://review.openstack.org/#/c/182590/

I've tried to reproduce this problem on Fuel 6.0.1 ISO #239.

I enterd password with dollar (Q$wer!123), added one controller node to the cluster and
started deployment process.

Deployment process finished successfully, but I ended up with inoprable cluster.
nova-compute service fail to start on controller, because it cannot interpolate variable $wer.

Pacemaker marks nova-compute service as 'Started', but actually it is constantly restarting and
it does not appear in 'nova service-list' output. There are no available hypervisors in OpenStack
to operate. So I think we should raise severity for 6.0.1 to High.
