[MTV-1880] Fix 'Project' name select issues

[jpuzz0]

Issue: https://issues.redhat.com/browse/MTV-1880
Design issue: https://issues.redhat.com/browse/HPUX-259

Summary

1. Fixed validation of create plan wizard for Project select so that it is required before proceeding to the next step
2. Updated behavior of project select in the create plan wizard so that all projects (namespaces) are shown instead of filtering them, and instead, the provider cards are filtered based on the Project selection made - only providers with namespaces matching the selected Project will be rendered. Added empty state view for when a Project is selected without any associated providers.

NOTE: All comments made here were addressed with the exception of #5 to rename the details "Namespace" label (was suggested to update to be named "Project). This is still being discussed as to what we might change the tooltip text to, since there are many references to the term "Namespace".

Hey @jpuzz0

Do you know if we have a JIRA ticket for the MTV project?
You missed our last conversation about PR's associated to JIRA ticket on MTV - each PR should have a reference in MTV project with ACK's. I would be happy to explain more on Slack.

@jpuzz0 Can you please also breakdown this PR into small PRs? Much easy to review and verify by QE when the PR is small and related to one issue...
At least it will be great if you can divide this into two PRs: one for the 'project field' feature fixes and the other for the 'plan name' feature.

Thanks!

@metalice
Yes, I had one open, and the ID is in the title/comment of the PR/branch, but forgot to link it. The JIRA link is in the description now.

@sgratch Sure, I'll break it down into 2 PRs. I'll keep this one just for "Project name" fixes and break out the "Plan name" feature.
