Support "IgnoreChanges" on migrations

[giggio]

There is no equivalent for IgnoreChanges when generating migrations right now. Not on powershell, or using ef migrations add. This needs to come to EF7 and is a fundamental part of the migration work, specially for apps that are working with existing tables.

This is probably just stating the obvious... but as a workaround for the moment you can generate a migration and then delete the code from the Up/Down methods.

Team Triage: Reopened the more general issue (#2167) to take a look at this and other existing database related functionality in migrations.

@rowanmiller #2167 is still closed...
