## Context
Field metadata service was reusing validators from
validate-**OBJECT**-metadata-input which were throwing ObjectMetadata
exceptions not handled in fieldMetadataGraphqlApiExceptionHandler and
were going to Sentry.
To solve the issue since this validator is associated with both fields
and objects I'm moving the util to the root utils folder of metadata
module and throwing a common metadata user input exception
We call convertExceptionToGraphQLError in the exception handler for http
exceptions but we don't take into account those that already are
graphqlErrors and because of that the logic of convertExceptionToGraphql
is to fallback to a 500.
Now if the exception is a BaseGraphqlError (custom graphql error we
throw in the code), we throw them directly.

Class exception for each metadata module + handler to map on graphql
error
TODO left :
- find a way to call handler on auto-resolvers nestjs query (probably
interceptors)
- discuss what should be done for pre-hooks errors
- discuss what should be done for Unauthorized exception
