feat: allow customization of log indicators with skin theme

[mikesmithgh]

Is your feature request related to a problem? Please describe.
Add fields to logs.indicator section of skin yaml to customize indicator colors (e.g., autoscroll, fullscreen, timestamps, wrap, etc)

Describe the solution you'd like
Add options to LogIndicator section of skin.
E.g.,

    logs:
      fgColor: *lightskyblue
      bgColor: *black
      indicator:
        fgColor: *dodgerblue
        bgColor: *black

Additional context
Source is currently hardcoding limegreen and gray https://github.com/derailed/k9s/blob/master/internal/view/log_indicator.go#L129

I may give this one a shot 🤷 but don't hold me to it 😂
