Default disable_ci_skip to true

[david-baylibre]

Is your feature request related to a problem? Please describe.

I think it would make sense to change disable_ci_skip default value to true for the following reasons:

• All filters are empty by default, disable_ci_skip introduces a filter in some way.
• On top of that, people do not benefit from PR fast check skipping repo download #425 which makes checks run instantly (skipping repo download), unless they set disable_ci_skip to true.

Describe the solution you'd like

Default disable_ci_skip variable to true

• OR -

Rename disable_ci_skip variable to enable_ci_skip (with default value set to false obviously)

Describe alternatives you've considered

Additional context
