Improved closing bracket indentation for vue/html-indent rule. (#1162)
- Added `closeBracket.startTag`, `closeBracket.endTag` and `closeBracket.selfClosingTag` options to `vue/html-indent` rule. So that the closeBracket offset value can be set for each tag type. - Changed `vue/html-indent` rule to calculate the base point of the indent offset of the closing bracket of the end tag by the start tag.
