Commit bae6435fd9 adds scaffolding for the
blueprint table. Blueprint features should be hidden behind experimental
flags. The new buttons related to creating blueprints and rebuilding
images in the header were not hidden behind the experimental flag, this
commit fixes that and does so.
bae6435fd9 also changed the header title
from "Image Builder" to "Images". This change has been a long time
coming - it is being left in for now. We may want to revisit the copy in
the popovers to align it as the term "Image Builder" is still being used
in those.
This commit:
1. Removes the header from the Data Driven Forms wizard
2. Adds padding around the in-page wizard so it is visually consistent
with the images table
3. Refactors the images table header into a re-usable component that is
now used in both the images table and the wizard
4. Allows the repositories table to fill the available vertical space in
the wizard
5. Adjusts the package dual list selectors so that they fill the
available horizontal space in the wizard
