chore: improve session logging

Adding a log line about the session's total schedulable capacities.

Recently there has been various changes in the session resource
handlings, and it would be generally useful to have a log line
about the cached resource, including TotalResource, TotalDeserved
and TotalGuaranteed.

Enhance capacity plugin queue attribute logs to include 'capability'
for both flat and hierarchical queues and distinguishing the log
line in the two cases.
