SEGMENT_API_HOST integrations['Segment.io'].apiHost cannot hit current host

[ewah]

To solve 3rd party script issues we want to proxy our own api.segment.io calls

We're ok having it on the same fqdn and routing back w/ nginx/cloudflare/cloudfront/etc.

But it looks like .send() does not give us an opportunity to put in send it as the same
originating domain.

would love for SEGMENT_API_HOST/apiHost just take "/v1", "/segment/v1"

  const apiHost = settings?.apiHost ?? SEGMENT_API_HOST
  const protocol = settings?.protocol ?? 'https'
  const remote = `${protocol}://${apiHost}`
  ....
  
    return client
      .dispatch(
        `${remote}/${path}`,
        normalize(analytics, json, settings, integrations)
      )
      .then(() => ctx)

just a note cdnURL will take in '' and '/segment' as prefixes to the current fqdn

export function loadLegacySettings(
  writeKey: string,
  cdnURL?: string
): Promise<LegacySettings> {
  const baseUrl = cdnURL ?? getCDN()

  return fetch(`${baseUrl}/v1/projects/${writeKey}/settings`)
