CBG-4600 apply networkType to cbgt

• move construction of options to a helper function
• replace gocbconnstr with the connstr package in gocb, these are the same packages
• Add networkType if applicable, following how this works https://github.com/couchbase/gocbcore/blob/f6c191fa62dd0fcc97e1219cdc9da2bb5f19891e/agent_config.go#L269 which is called from

  sync_gateway/base/gocb_dcp_client.go

  Line 360 in fefbba4

  connStrError := agentConfig.FromConnStr(connStr)

Pre-review checklist

• Removed debug logging (fmt.Print, log.Print, ...)
• Logging sensitive data? Make sure it's tagged (e.g. base.UD(docID), base.MD(dbName))
• Updated relevant information in the API specifications (such as endpoint descriptions, schemas, ...) in docs/api

Integration Tests

Pull request overview

This PR updates Sync Gateway’s DCP sharded import (cbgt manager setup) to propagate the network connection-string option into cbgt/gocbcore configuration, and refactors connection-string parsing to use gocbcore/v10/connstr instead of the older gocbconnstr package.

Changes:

• Switch connection-string parsing to github.com/couchbase/gocbcore/v10/connstr and add a shared helper for typed option retrieval.
• Refactor cbgt manager option construction into cbgtManagerOptions, and apply network as gocbcoreIOConfigNetworkType when present.
• Add/extend unit tests covering typed option parsing and cbgt manager option building for network and kv_buffer_size scenarios.
