added quiet feature to read_params

Added a quiet feature to read_params to suppress messages and warnings from reading with dso get-config

I'm wondering if this should be made consistent with the CLI:

• also add verbose flag
• quiet can take an integer for different "levels" of quiet:

--quiet    -q  INTEGER RANGE  Reduce verbosity. -q disables info messages, -qq disables warnings. Errors messages cannot be disabled. The same can be achieved by setting the env var DSO_QUIET=1 or DSO_QUIET=2, respectively.                                                                                                                                       
--verbose  -v                 Increase logging verbosity to include debug messages. The same can be achieved by setting the env var DSO_VERBOSE=1. 

Also note that it would be possible to set --quiet in dso -qq exec quarto . or globally using

dso:
  quarto:
     before_script: "export DSO_QUIET=2"

and it would be quiet only when executing from the command line, but not when running interactively.

@grst we can definitly discuss this. at the moment the verbose mode introduces bugs in the notebook display of Rstudio server.

I tested and the quiet function works as expected.
