Add an example passing parameters to the install-deps command

[jlgimeno]

Describe Request:

Occasionally repos are set up with a different requirements file than requirements.txt. There is no documentation for passing parameters to commands in orbs

Examples:

From my own config.yml: executor: python/default steps:

• checkout
• python/load-cache
• python/install-deps: dependency-file: dev-requirements.txt local: true
• python/save-cache

There was no documentation that both parameters had to be passed, even if one of them remains the default (local in this case). This would save a considerable amount of time to users that are not aware of this requirements.

Hi there! The documentation was lacking prior to the 1.0.0 release of the orb. With the latest release, you'll find better examples, however the ability to specify a requirements.txt was removed. In the PR linked, I have added the ability to specify a different requirements.txt or even a setup.py to be used in the command.
