[system test] All indexes are wiped out on the UI ( Index Tab, main console, etc) after a cluster reboot

0. create cluster, create indexes gsi on the buckets - all online and ok
1. Load items on the buckets ( attached screenshot for item distribution)
2. Reboot the cluster

• Index Tab- Zero indexes present
• Individual buckets from the main console - shows no presence of indexes

Note : I had filed a bug earlier about Index stats being "N/A" for some nodes and this cluster now shows nothing present for indexes - which is very odd.

The index directory contains teh index definition, though none of the queries can use any of the indexes

• Query either hangs
• shows index stale meta data
