Migrate to Web3.py v5 (#2038)
* Install Py packages in dep. order, not in parallel

Install Python packages in dependency order, not in parallel.

* sra_client.py: Add `./setup.py clean`

* Fix python package dependency ordering...

...and include a script to produce the proper ordering.

* sra_client.py: reformat whitespace in doctest

* contract_wrappers.py: don't auto-import wrappers

This was discovered while minimizing CircleCI steps to dianose a problem
with running the Launch Kit Backend in CircleCI.

These classes should be imported via the
zero_ex.contract_wrappers.exchange and
zero_ex.contract_wrappers.erc20_token modules, respectively.  We
permitted importing them from just zero_ex.contract_wrappers back when
they were the only wrappers we had, but now that we have so many
different contracts being wrapped, this is just another list to keep
manually updated (which, obviously is error prone, since it slipped
through the cracks already), so it's better to just not support this
type of import.

* abi-gen/Py: doc contract method attributes

Without this, generated documentation was not including the class
members that represent the contract methods, rendering the usage
unclear.

* sra_client.py: disable tests in CI

* abi-gen/Py: strip repeated spaces from devdoc

* contract_wrappers.py: gen docs for all wrappers...

...except for the dummy tokens.

* sra_client.py/test: change launch kit docker image

Previously these teses were using 0xorg/launch-kit-ci, but that was a
one-off thing created just for CI, back before there was a regularly
maintained docker image of Launch Kit.

Changed to use 0xorg/launch-kit-backend since it's regularly
maintained/updated.

Because the -backend image is using a different Linux distribution
(Alpine), the commands used to wait for ganache startup also had to
change.

The tag used, 74bcc39, is provisional due to the pending Issue at
https://github.com/0xProject/0x-launch-kit-backend/issues/73 .  When
that issue is resolved, the tag suffix on the imag name should be
removed.

* Migrate from Web3.py 4.x to 5.x

* sra_client.py: checksum address in doctest

Due to problem with launch-kit-backend, documented at
https://github.com/0xProject/0x-launch-kit-backend/issues/73 ,
we need to checksum the makerAddress, in the order retrieved from the
relayer, before filling it, otherwise Web3.py gives this error:

InvalidAddress('Web3.py only accepts checksum addresses. The software
that gave you this non-checksum address should be considered unsafe,
please file it as a bug on their platform. Try using an ENS name
instead. Or, if you must accept lower safety, use
Web3.toChecksumAddress(lower_case_address).',
'0x5409ed021d9299bf6814279a6a1411a7e866a631')

* Update CHANGELOGs

* sra_client.py: make CHANGELOG be REVESE chrono.

Formerly CHANGELOG was in chronological order.  Now it's in reverse
chronological order.

* abi-gen/Py: fix missing space in sanitized devdoc

3099ba71eb New demos for Python packages (#1734)
End-to-end demos of constructing and signing an order and submitting it to a Relayer.  Docs are generated from the code, and include usage examples that are verified through automated testing.

Python contract demo, with lots of refactoring (#1485)
* Refine Order for Web3 compat. & add conversions

Changed some of the fields in the Order class so that it can be passed
to our contracts via Web3.

Added conversion utilities so that an Order can be easily converted to
and from a JSON-compatible dict (specifically by encoding/decoding the
`bytes` fields), to facilitate validation against the JSON schema.

Also modified JSON order schema to accept integers in addition to
stringified integers.

* Fixes for json_schemas

Has-types indicator file, py.typed, was not being included in package.

Schemas were not being properly gathered into package installation.

* Add test/demo of Exchange.getOrderInfo()

* web3 bug workaround

* Fix problem packaging contract artifacts

* Move contract addresses to their own package

* Move contract artifacts to their own package

* Add scripts to install, test & lint all components

* prettierignore files in local python dev env

* Correct missing coverage analysis for sra_client

* CI cache lint: don't save, re-use from test-python

* tag hacks as hacks

* correct merge mistake

* remove local strip_0x() in favor of eth_utils

* remove json schemas from old order_utils location

* correct merge mistake

* doctest json schemas via command-line, not code
