R2.2 - Fixed/Updated euca2ools Describe Outputs

Tested fix by doing the following:

* creating eucalyptus-sos-plugins package
* installing package on 3.3.2 cloud
* ran the following command
```
sosreport -o eucacore,eucadb,eucafrontend
```
* confirmed files were populated and named based upon fix.

Fix added the following:

* used euca-get-credentials to download eucalyptus/admin credentials to be used with euca-describe-* for Cloud Component statuses
* created ini file under /etc/euca2ools/conf.d/ to be used with euca-describe-* for Cloud Resources
* added a cleanup to remove all temporary directories and file associated with credential management.
