Add action schema to track wallet and stake events

[hawyar]

I removed the wallet schema and replaced it with action.schema.json to hold the wallet and stake events per our online discussions with @elizyoung0011. Updated CDK analytics script to create the required buckets and tables

I added a$comment field to the analytics schema files. That will make it easier for me to do code gen only on those files.

There is an output bucket but I don't think we are currently using it as the output location of the Athena queries. It is easy to set the output location in the console but I couldn't find a outputLocation or a similar option to pass it to the new glue.Table constructors.

Very nice. Want to just keep the output bucket? No prob. Are we bumping the data version for this PR? Let's take a quick look at retention policies for Glue database/tables and see if we can't add one to the resources in this PR.

Yes lets keep the output bucket so the client (whoever callsAthena) can set the query output to that bucket. That works for now
