Bump pipdeptree from 1.0.0 to 2.0.0 in /cccatalog-api

[dependabot]

Bumps pipdeptree from 1.0.0 to 2.0.0.

Changelog

Sourced from pipdeptree's changelog.

2.0.0 (stable)

• Support for running in the context of a virtualenv (without installing pipdeptree inside the virtualenv)

• Avoid crash when rendering cyclic dependencies

• Fix graphviz (dot file) output

• Handle a (rare) case while guessing version of a package

• Migrate from travisCI to Github workflows

• Improve integration tests

2.0.0b1 (beta version)

• In this first beta release targeting 2.0.0, the underlying code is heavily refactored to make different CLI options work well with each other. This was a serious limitation in older version <=1.0.0 which made it difficult to extend the tool.

  For more information about the plans for 2.0.0 release, please check docs/v2beta-opts.org file.

  • The --reverse, --packages and --exclude flags now work with --json-tree and --graph-output
  • Dropped support for python 3.3 and added support for python 3.7 and 3.8

• Another problem with older version was that tests setup was convoluted and involved loading packages pickled from one env into the current env (in which tests are run). Moreover there was no separation between unit tests and integration tests (flaky)

  • Tests have been separated into 2 suites (1) unit tests that totally rely on mock objects and run on every commit ( travis.ci) and (2) end-to-end tests that need to be run manually.
  • The test setup for end-to-end tests has been greatly simplified although the "flakyness"" still remains because these tests are run against unpinned versions of pip. However this is by design because we want to know when pipdeptree fails with a new version of pip.

• Move continuous integration from Travis to Github Actions.
