Mark a vertex o-series connection as installed

Enable Vertex tax calculation on a connection once its external system's Vertex connector is installed, and sync existing registrations. `installationWarnings` lists non-blocking setup issues found along the way. Works for a connection of any source that uses Vertex as its tax engine, not only a Vertex O-Series connector connection. Returns 400 if a NetSuite connection cannot scaffold tax types (tax calculation is disabled again in that case). Returns 404 if the connection does not exist or belongs to an organization your credential cannot access. A multi-org credential must send an `Organization-Id`, `Connection-Id` or `Entity-Id` selector, or gets a 400.

  allowed values: ACTIVE, INACTIVE, CONNECTION_ERROR
storeName (string) - Human-readable store or account name for the connection; an empty string when the connection has none.
