Chain name aliases

What is the current behavior?
Every chain has a unique network identifier, like mainnet, matic, xdai. Some of these chains were renamed but their unique identifier stayed the same. Eventually, new developers will be confused because they do not intuitively understand why a subgraph running on Polygon should have matic as network identifier. Same for xDai which was renamed to Gnosis Chain.

Though, just changing these network identifiers would break all existing subgraphs that still have matic as network and not polygon.

What is the expected behavior?

I would recommend to introduce network identifier aliases, so we can start to communicate the new names but still support the old ones.

Example:

matic -> polygon
xdai -> gnosis-chain

Etc.

El issue no menciona archivos, pruebas ni puntos de entrada. Empieza por localizar cómo graph-node valida y utiliza los identificadores de red, y después sigue las rutas de configuración y de los subgraphs afectadas. Se considera terminado cuando se aceptan identificadores renombrados como polygon y gnosis-chain, mientras los subgraphs existentes de matic y xdai siguen funcionando.
