Description of problem:
I was trying to import two different manifests in two different org's and got following errors:

katello> provider import_manifest --org ACME_Corporation --name "Red Hat" --file /root/stageSamTestSimple20Nov2011.zip
Manifest imported                     
katello> 

First import succeeded and on second import got: 

katello> provider import_manifest --name "Red Hat" --org sghai_org --file /root/stageManifest06October2011.zip
Importing manifest, please wait... Manifest import for provider [ Red Hat ] failed, Candlepin::Owner: 409 Conflict {"displayMessage":"Import is older than existing data"} (POST /candlepin/owners/sghai_org/imports)

then I tried --force option and it was imported successfully:

[root@dhcp201-123 ~]# katello -u admin -p admin provider import_manifest --org sghai_org --name "Red Hat" --file /root/stageSamTestSimple20Nov2011.zip --force
Manifest imported

How reproducible:
always

Steps to Reproduce:
1. Import Nov's simple manifest in org1 
2. Then try to import Oct's manifest in org2 and without --force
3.
  
Actual results:
importing manifest, please wait... Manifest import for provider [ Red Hat ] failed, Candlepin::Owner: 409 Conflict {"displayMessage":"Import is older than existing data"} (POST /candlepin/owners/sghai_org/imports

Expected results:
I think if user tries to import different manifests in different org's then no error should be raised. 

or User should get a proper *warning* message like: Import is older then existing data, please try with --force option to import manifest.
