Remove old import formats

[rileykarson]

In some cases, such as SQL Database with {{instance}}:{{name}} form, we support import formats with non-standard delimiters. We should remove them as part of 3.0.0 to ensure consistency across resources and to simplify MM generation.

If it's impossible to remove in some cases - say, if / is an ambiguous character - we should instead add support for different delimiters to MM.

@slevenick: Do you think you got all these in the process of the id changes?

[slevenick]

I don't think so! I definitely changed a couple of them that used : or ., but I didn't change ones where a self link wouldn't be helpful or applicable, like organization policies

This should be done as part of 3.0.0.
