* Set up CI with Azure Pipelines

This commit adds the CI configuration for running sphinx builds in CI. [skip ci]

* Add missing dep and start caching pip

* Install pandoc and graphviz

* Add cvxpy install for aer noise transformations

* Move aqua tutorials that depend on CPLEX to legacy_tutorials

There are 2 aqua tutorials that do not work unless CPLEX is installed.
CPLEX is too involved and difficult to install in CI. It is also
proprietary software which prohibits installing it in CI (since a CI
system can't agree to the license terms). Honestly, I'm not entirely
sure why aqua has modules in it that depend solely on having proprietary
software installed, it feels like there should be an open alternative or
if there is one already the tutorial should leverage that. To make the
docs buildable this commit moves these problematic tutorials to the
legacy directory so they're not built/run by default.

* Workaround terra mpl drawer bug

There is a bug in the mpl drawer in 0.19.0 (and 0.19.1) release where a
custom instruction does not draw without a label parameter set. This
will need to be fixed in terra, but in the meantime this worksaround the
bug by manually setting a label.

the MSB is left-most, indexed with 0.

…g_started_with_qiskit.ipynb

Update 1_getting_started_with_qiskit.ipynb

The transpiler passes tutorial was previously replacing the 'properties'
attribute of the FakeTokyo backend with an empty dictionary {}. However,
this is a type violation as properties is defined (and has been for a
very long time) as a method in the base abstract backend class. [1] This
didn't block anything because nothing the call path of the notebook was
using properties as a callable before. But in terra 0.15.0 this has
changed and backend.properties() is accessed in the setup for a
transpilation and this is causing a failure. This commit removes the use
overloading of the attribute as it doesn't seem to serve a purpose
anymore (I presume it was there for when NoiseAdaptiveLayout was in
level 3) which will unblock Qiskit#998

…tutorials#1251)

This PR updates the pulse drawer usage to be compatible with both v1 and v2 drawer.
In qiskit 0.19.0 the `Schedule.draw()` method will be updated to use the v2 drawer,
which has different arguments. The v1 usage patterns have been deprecated for some
time and this commit updates the tutorial using the drawer to generate visualizations
that work with either. This way the tutorial can be used with 0.18.x and 0.19.x.

…skit/qiskit-tutorials#1254)

This is a follow-up to Qiskit/qiskit-tutorials#1253 and is updating the
usage of the pulse drawer to avoid deprecated functionality.
This is a blocker of Qiskit#7267 which is finishing
those deprecations and trying to remove the deprecated usage
patterns.
