docs: Insert the value at the specified point in the template uri.
  <p>
  This method is poorly named has undocumented behavior. When the value contains a fully
  qualified http request url, the value is always inserted at the beginning of the uri.
  </p>
  <p>
  Due to this, use of this method is not recommended and remains for backward compatibility. It
  has been replaced by {@link RequestTemplate#target(String)} and will be removed in a future
  release.

  @param pos in the uri to place the value.
  @param value to insert.
  @return a RequestTemplate for chaining.
  @deprecated see {@link RequestTemplate#target(String)}
