Description of problem:
If a customer has no management entitlements, we should either not show the
'Manage' and 'Clear' buttons on top right of their accounts when logged in, or
not that they have no management entitlements, so that when they click the
button they are given a nice page saying what it does and what they need to
purchase to use it, rather than the current, rather ugly, permission denied page. 

Version-Release number of selected component (if applicable):
RHN Hosted 4.1

How reproducible:
Always

Steps to Reproduce:
1. Login to webQA as rhnuser that does not have any management entitlements (nor
provisioning)
2. Click on 'Manage' button
  
Actual results:
https://rhn.webqa.redhat.com/network/systems/ssm/index.pxt

entitlement (which they can purchase).
