Provide a way to only expose a set of given tables and/or views out of a DB

[jrevault]

Hi The Guild team

For instance my source is a legacy MySql DB with lot's of tables (could be a Postgres too in a near future). I created a view that represents exactly what I need to expose in graphql, and it would be great just to expose this view(s).
Would be great if the way to expose views would be the same as exposing tables.

I created a branch (https://github.com/jrevault/graphql-mesh/tree/1045-tables-config) with a naive implementation, should I push the PR and link it to this issue ?
Recap of the changes :

• Added to MySQLHandler a 'tables' config (takes a comma separated list of tables)
• In mysql/src/index.ts : reads the new config.tables and if it is null or if values matchs tables names from getDatabaseTables, goes with generation
  Unfortunatly I have no idea of how to tests (I launched 'yarn test' everything is green) but can't test my very specific modifications.

If you prefer doing it np 👍
