This allows the user to only show logs from a specific date span.
For that two date picker and a 'Update' button were added to the
header bar.
For the until date we assume always 23:59:59 o'clock, as witouth
a specific time journalctl assumes 00:00 which would result in an
empty log if we only wanted to look at todays log.
As the LogView is shared with others (e.g. ceph log) use an boolean
variable to set if we want to show those date pickers)
Fixes timeout when the user has a long uptime and or persistent logs
Do not only allow root@pam to admin ceph server as some user do not
want to allow root logins and users with the Sys.Modify permission
should be able to modify ceph related stuff.
We use basically the following permissions:
Sys.Modify:
for any delete, add, modify action (POST, PUT, DELETE)
Sys.Audit and Datastore.Audit:
for any status/information view action (GET)
Sys.Log:
for viewing the Ceph log (was already implemented)
We have two exceptions creating and destroying osds. Those may only
be done by 'root@pam' for security reasons.
Also show users with any of those capabilities the ceph tab in the
web GUI.
