Overview of change:

Add the hasFix property to the metadata of the indent rule.

The docs for this rule mention auto-fixing, but the green "🔧 Has Fixer" badge doesn't appear, which could lead people to assume (like I did) that this rule has no fixer.

Future Suggestions:

Perhaps make the hasFix property required instead of optional so that rule authors are required to correctly set this properly. Further more, maybe add a check to see if hasFix: false is set but the rule contains a call on the Lint.Replacement, or Lint.RuleFailure has something passed into the 6th parameter for a fix.

I think the docs description is misleading then. We need #3395 before declaring this rule as having a proper fixer.

[ChrisMBarr]

I mean... it does have a fixer right now technically... but I see what you mean since the current one doesn't work in 100% of cases.

The docs do mention that it only works when certain options are set though, which seems sufficient enough to add this badge.

My use case & thought process: I work on a project with mixed tabs/spaces and I want to normalize them.

I enable this rule to see all the violations... wow there are a lot! I check the docs in hope of an auto-fix... nope, I guess I have to do all these fixes manually! This sucks... oh wait, it does have an auto fix. This is just a documentation issue,

[adidahiya]

ok, fair enough, if you think the documentation caveat is good enough :)

[adidahiya]

hm actually we should elaborate the docs about the required option for auto-fixing... we should say it doesn't auto-fix indent size, just indent style (tab vs. spaces)

@adidahiya Check out my latest changes, would adding text like that be sufficient?

@ChrisMBarr looks good, but linting failed
