Murano- Package Dependencies like glance images with agent not downloading

[Ajith Narayanan]

After Murano Installation

1) While packages are being imported, the dependent glance images with murano agent download starts and remains in 'SAVING' mode forever.

2) The murano logs keep displaying below DEBUG message and the project list in the horizon dashboard does not show up the list of projects due to this authentication problem.

DEBUG:keystoneauth.session:Request returned failure status: 404

This means, that murano passed the ball to glance. Murano does not actually download the images itself, but rather relays on glance's copy-from functionality from v1 api. If the image is saving too long — there might be a networking issue with downloading it
