Large Cloudformation Templates (>51,200 Bytes) cause error on alias remove

[mbruning24]

We have a particularly large serverless package (~15 functions) and when we try to remove an alias on it, we get the error:

'templateBody' failed to satisfy constraint: Member must have length less than or equal to 51200

It seems to actually remove the alias, but the serverless execution does not run to completion. Is there a way for the plugin to use S3 as a mechanism for CF templates that are really really big?

@mbruning24 Thanks for the report. Oh, I think you're right. Deployment & co use S3 already (in the same way as Serverless does), but remove alias also generates a new CF template for the base stack. I think I just missed to apply the same mechanism there.

It would be great if someone could provide a PR to solve the issue.

I hit that same issue today as well. @HyperBrain are you working on this? Not sure where to start on PR myself but if you point me I can give it a go.

@dgoradia Thanks for helping out 👍 . The remove command is a separate file and the specific errorneous line is here: https://github.com/HyperBrain/serverless-aws-alias/blob/master/lib/removeAlias.js#L158

Instead of putting the template into the TemplateBody property, it should be uploaded to S3 (same as with the deploy) and only the S3 object should be referenced there.

@HyperBrain I took a stab at this. Would appreciate any feedback. https://github.com/HyperBrain/serverless-aws-alias/pull/150
