[feat] Allow disabling pipeline hooks from the command line

[vkarak]

I'm using --disable-hook as a command line option, which can be chained, for consistency with the rest of the options.

This PR also changes the output in detailed listing to the following:

- OpenCLCheck:
    Dependencies:
      <none>

    Description:
      OpenCLCheck

    Environment modules:
      craype-accel-nvidia60

    Location:
      /users/karakasv/Devel/reframe/cscs-checks/prgenv/opencl_check.py

    Maintainers:
      TM, SK

    Node allocation:
      standard (1 task(s))

    Pipeline hooks:
      pre_compile: setflags, cdt2006_pgi_workaround

      production, craype

    Valid environments:
      PrgEnv-cray, PrgEnv-pgi

Short listing is also slightly changed (no indentation and path is quoted):

- OpenCLCheck (found in '/users/karakasv/Devel/reframe/cscs-checks/prgenv/opencl_check.py')

Fixes #1273.

Still todo:

• Update the documentation.

Note: This PR needs to be merged after #1461.
