Expand pip commands into separate entries

[jplock]

My serverless.yml file looks like:

pythonRequirements:
    pythonBin: ".venv/bin/python3"
    invalidateCaches: true
    pipCmdExtraArgs:
      - "--trusted-host pypi.python.org"
      - "--trusted-host pypi.org"
      - "--trusted-host files.pythonhosted.org"

Before this change, the generated pipCmds looked like:

pipCmds: [
  [
    '.venv/bin/python3',
    '-m',
    'pip',
    'install',
    '--trusted-host pypi.python.org',
    '--trusted-host pypi.org',
    '--trusted-host files.pythonhosted.org',
    '-t',
    '~/Library/Caches/serverless-python-requirements/01dde858536f71d67120395d14566ab6f37cce626069dc5d99d750fcd314e5c2_slspyc',
    '-r',
    '~/Library/Caches/serverless-python-requirements/01dde858536f71d67120395d14566ab6f37cce626069dc5d99d750fcd314e5c2_slspyc/requirements.txt',
    '--cache-dir',
    '~/Library/Caches/serverless-python-requirements/downloadCacheslspyc'
  ]
]

And resulted in this error:

Error --------------------------------------------------
 
  Error: STDOUT: 
  
  STDERR:

After this change, the pipCmds looks like which seems to pass successfully to pip:

pipCmds: [
  [
    '.venv/bin/python3',
    '-m',
    'pip',
    'install',
    '--trusted-host',
    'pypi.python.org',
    '--trusted-host',
    'pypi.org',
    '--trusted-host',
    'files.pythonhosted.org',
    '-t',
    '~/Library/Caches/serverless-python-requirements/01dde858536f71d67120395d14566ab6f37cce626069dc5d99d750fcd314e5c2_slspyc',
    '-r',
    '~/Library/Caches/serverless-python-requirements/01dde858536f71d67120395d14566ab6f37cce626069dc5d99d750fcd314e5c2_slspyc/requirements.txt',
    '--cache-dir',
    '~/Library/Caches/serverless-python-requirements/downloadCacheslspyc'
  ]
]

The build failures don't seem related to this change.

@dschep any thoughts on this one?

@dschep I was wondering when the next release is going to be released that includes this change? Thanks.
