[SIGMON-299] Backwards compatible QueryBuilder

Context

• Main goal of the task was to reimplement QueryBuilder using lhcsmapi.api.query to validate the latter
• task: https://its.cern.ch/jira/browse/SIGMON-299
• lhc-sm-api MR: lhc-sm-api!160 (merged)

What was done

• since functions from query.py unpack the single df, in certain places [0] was removed
• calls to the functions that query and analyse 'pc events' were adapted to the new signatures
• references were adapted manually (log messages were fixed, new messages were added, old ones removed)
• HTML reports were replaced

TODO

• integrate with https://its.cern.ch/jira/browse/SIGMON-341
• deal with the SettingWithCopyException in https://its.cern.ch/jira/browse/SIGMON-342
