chore: support workspace profile setting

[ecmadao]

Support configuring the workspace profile setting, thus we can support the whole workflow for users/members/gitops without the Bytebase UI. For example:

resource "bytebase_setting" "workspace_profile" {
  name = "bb.workspace.profile"

  workspace_profile {
    external_url = "https://bytebase.example.com"
    domains      = ["bytebase.com"]
  }
}

resource "bytebase_group" "developers" {
  depends_on = [
    bytebase_user.workspace_dba,
    bytebase_user.project_developer,
    # group requires the domain.
    bytebase_setting.workspace_profile
  ]

  email = "[email protected]"
  title = "Bytebase Developers"

  members {
    member = format("users/%s", bytebase_user.workspace_dba.email)
    role   = "OWNER"
  }

  members {
    member = format("users/%s", bytebase_user.project_developer.email)
    role   = "MEMBER"
  }
}
