Description of problem:

Description of problem:

Pulp-admin supports login command from one user to another without prior logout.
So far, every new login command rewrite/removes the granted certificate of the previous user. After logout command the user doesn't have his session back with a granted certificate anymore. So s/he has to login again.

Nested sessions like in bash shell would be nice feature especially for users with admin roles.

Steps to Reproduce:

pulp-admin login -u admin -p admin

Successfully logged in. Session certificate will expire at Oct 9 20:19:42 2015
GMT.

Authentication Failed

Use the login command to authenticate with the server and download a session
certificate for use in future calls to this script. If credentials were
specified, please double check the username and password and attempt the request
again.

Expected results:

1. Log as user #1
2. Execute some pulp-admin commands without -u/-p options
3. Log as user #2 without logout from the user #1 session
4. Execute some pulp-admin commands without -u/-p options as user #2
5. logout
6. return back to the session of user #1 and be able to execute pulp-admin commands without -u/-p options since the certificate of user #1 should be still valid
