handle users pre-existing project in OSO gracefully

[kbsingh]

In many cases, when a user logs into OSIO, they might already have some project / namespace or app deployed in their OSO space. Since we need to config this namespace as the users dev environment, we should handle the condition gracefully, doing either one of the following options:

• When the user logs into OSIO, they are asked to link their OSO account - at this point, we should sanity check their OSO account to ensure its in a good state, if not, offer the user a choice to clean it up for them
• Alternatively, we just use whatever project the tenant already has setup, as their dev environ and just modify that space with whatever acl's and privileges we need.

Sub-task(s):

• Remove user's OSO project when resetting his/her environment Remove user's OSO project when resetting his/her environment fabric8-services/fabric8-tenant#469
• Detect if the user to init on Tenant already has a project on OSO Detect if the user to init on Tenant already has a project on OSO  #1446

The first choice sounds like a smaller task - build a tool to examine a user's environment, and if the state does not match our predefined concept of a "good" state, clean it up.

The second choice sounds more involved as we would be performing discrete modifications to a user's environment.

The challenge is that this project/dev environment needs to live in a space somewhere. I think the ideal situation here long term is that we would have a unique UI flow to handle this situation, as it may be a likely situation for many people on-boarding into OSIO. I can add this to the UX Backlog. If we want to do a fix until then, I agree that asking the users to clean if we see this is a fine hold-over until we can implement the proper pathway.
