Implement stpipe run CLI command

[stscijgbot-jp]

Issue JP-1894 was created on JIRA by Edward Slavich:

Implement the "stpipe run" CLI subcommand.  Here is the tentative help output for the command:

$ ./stpipe run -h
usage: stpipe run [-h] [--config <path>] [-d] [-p <name>=<value>] [-v] <class> <input-file>

run a step or pipeline

positional arguments:
  <class>            step or pipeline class name (case-insensitive, module path may be omitted for unique class names)
  <input-file>       input dataset or association

optional arguments:
  -h, --help         show this help message and exit
  --config <path>    config file (use 'stpipe print-config' to save and edit the default config)
  -d, --debug        debug logging (DEBUG level)
  -p <name>=<value>  override an individual step or pipeline parameter (use 'stpipe describe' to list available parameters)
  -v, --verbose      verbose logging (INFO level)

examples:
  run a pipeline with default parameters recommended by CRDS:

    stpipe run jwst.pipeline.Detector1Pipeline dataset.fits

  run a pipeline with parameters specified in a local config:

    stpipe run --config config.asdf jwst.pipeline.Detector1Pipeline dataset.fits

  override an individual pipeline parameter:

    stpipe run -p save_calibrated_ramp=true jwst.pipeline.Detector1Pipeline dataset.fits

  override an individual step parameter:

    stpipe run -p jump.rejection_threshold=3.0 jwst.pipeline.Detector1Pipeline dataset.fits

See #8 for more discussion.
