Patch Request to Update Destination Namespace

[danieldiamond]

Tell us about the problem you're trying to solve

I am wanting to add a customformat destination namespace but the current POST request requires the full syncCatalog included in its schema instead of referencing existing.

Describe the solution you’d like

I would like a PATCH request that simply takes the following schema:

"connectionId": uuid,
"namespaceDefinition": "customformat",
"namespaceFormat": "new_schema"

Describe the alternative you’ve considered or used

I looked into adding this simply PATCH path in the openapi config.yaml but it's proving somewhat difficult given the way it's structured.

This approach DRY up the PATCH <- POST <- GET inheritance chain looks extremely appealing regarding this issue however I imagine that's a significant overhaul of the inherent API structure.

Are you willing to submit a PR?

I tried to look into this and would happy to submit a PR, but would definitely need some pointers on how to start e.g. a blueprint of what the patch request would look like.
