[CI] Fix gate

This patch contains multiple fixes to unblock the gate:

1. use appropriate version of tempest repos

glance-secure-rbac-protection-functional job is failing as it uses too
recent version of tempest plugin which is not compatible with yoga
branch anymore [1]. This patch uses yoga-last tagged tempest and plugin
for the job.

2. drop centos-8 based job

glance-multistore-cinder-import-fips used centos-8 based nodeset which
was dropped from CI config (due to centos-8 reached End of Life)

[1] "ERROR: Package 'glance-tempest-plugin' requires a different
     Python: 3.8.10 not in '>=3.9'"
