Improve formatting of text blocks by Checkstyle TextBlockGoogleStyleFormatting

Hello!

We're using Checkstyle's `TextBlockGoogleStyleFormatting` and it would be nice Eclipse formatter would support it.

Currently we use 'Text block indendation: indent on column' which in this case caused undesired result

```
String hello =
"""
world
go
""";
```

-->
```
String hello =
"""
world
go
""";
```

which triggers Checkstyle `'"""' has incorrect indentation level 8, expected level should be 12.`

Could this 'column' formatter be improved?
