[Feature request] Disable color logs when not a terminal

[yermulnik]

Is your feature request related to a problem? Please describe.
At the moment tfswitch outputs logs with colors no matter whether it is run interactively or from within automation. Along with this when running within CI/CD or when tfswitch output is piped to another command or is written to a log-file it may be desired to log to console w/o colors to avoid vomiting console with escape sequences.

Describe the solution you'd like

• Default behavior: color output (same as it is at the moment)
• Non-terminal (non-interactive): force no color automatically (and add --force-color cmdline arg so users can enable color output explicitly) OR add --no-color cmdline arg to let user decide explicitly per use-case (additionally consider NO_COLOR env var: https://no-color.org/)
  • Add respective TOML config option for whichever option is considered

💡 Forcing color in non-interactive mode might be preferred e.g. when running within CI/CD pipeline that supports rendering ANSI escape sequences (e.g. https://plugins.jenkins.io/ansicolor/).

I guess this could be done at the same time as #451

"at the same time" as in you could be working on both? 🙏🏻
I think we should try and split different features into different PRs.
