Tell users when there is no data available in Daily Report

Here is the text from the bug:
If there is no metering data from the period selected,
user sees panel with no tables. It would be nicer to tell user that this is because there is no data to show.

The Daily Report displays one table per project. Since there is no data, then there are no tables.
This change displays the string "No data available" in this situation. This is the same
behavior as the Stats tab in the same Resouce Utilization Panel.

Create links in LBaaS detail pages

LBaaS detail pages contains many UUIDs and it is not human-friendly.
This commit replaces UUIDs with name or similar strings and
add links to details of corresponding resource.

In addition, some columns are added to health monitor tables
because UUID and monitor type are not enough to identify
health monitors.

Add tox env to build docs

In django-based projects, we need to specify DJANGO_SETTINGS_MODULE
when running docs build. It is required to addresses the warnings of
docs build job in the gate.

This commit also changes run_tests.sh --docs to use "python setup.py
build_sphinx" to match tox docs env. This change addresses all sphinx
build warning except keystone v3 related following warning.
I believe it is useful.

on window resize. This behavior should be optional and not the default.
This patch ensures that by default, charts do not automatically redraw.

Perform natural sorts on "Hostname" column on the Hypervisors panel

The API calls just return the results in who-knows-what order, so
explicitly sort them so they make sense.  Also tell jquery-tablesorter
how to do natural sorts, so that the results continue to make sense
when the users fidget with them.
