Support routing metrics to different DSNs in MFE setup

[chargome]

Currently metrics will be sent on the client that lives on the current scope:

sentry-javascript/packages/core/src/metrics/internal.ts

Line 163 in 2f0d9dc

const currentScope = options?.scope ?? getCurrentScope();

We want to provide an easy way for routing metrics to different DSNs just like we do with errors.

Hey @chargome , If not being worked internally mind if I take this up ?

[chargome]

Hey @harshit078, yeah feel free to pick this one up! Keep in mind that we somehow need to map metrics to a specific FE, most likely with attributes. Here are some docs that describe how we currently handle things with errors. Before going into implementation maybe post a quick proposal in here so we're aligned.

sure @chargome , I'll keep in mind before implementing. I think there is some issue with the attachment of docs, can you re-attach them ? Thanks !

Yep, updated!
