Disable progress and colors when not running on a tty

[francois2metz]

Is your feature request related to a problem? Please describe.
When running steampipe on Github Actions or similar, steampipe output the progress of the installation of plugins, database initialization, and control checks.

Describe the solution you'd like
It would be nice if by detault, if steampipe is not running on a tty, any progress or ansi colors are disabled.

Describe alternatives you've considered
When running mods/benchmarks/controls it's possible to use the flags --progress=false and --theme plain.

Additional context
Here is the sample output of installing a steampipe plugin on GitHub actions.

Nice idea @francois2metz ... perhaps we can set the internal flag at the start of the run based on whether we detect a terminal or not?
