Inflection Singular table names exclusion configuration

[danicc097]

Fixes #1526

Not a fan of exclude_table_names being so ambiguous, but emit_exact_table_names is already taken. Any ideas for that or is it good enough?

The code looks good, but I think you're right that exclude_table_names isn't a good name. I'll think about some alternatives that we can use.

[kyleconroy]

Let's go with inflection_exclude_table_names. It's still not great, but I want to unblock us.

@danicc097 You'll need to rebase as the configuration / proto files have changed.
