Build modified streamline images

The official image from streamline does not currently work for the arm64
platform. As a temporary measure, the source code and docker build scripts
have been lifted from the official images and are used to build locally.

Some additional modifications are made to reduce overall image size, these
are documented in docker/README.md

+ * Redraw the table (i.e. `fnDraw`) to take account of sorting and filtering,
+ * but retain the current pagination settings.

+ * DataTables 1.10+ provide the `dt-api draw()` method which has this ability
+ * built-in (pass the first parameter to the function as `false`). As such this
+ * method is marked deprecated, but is available for use with legacy version of
+ * DataTables. Please use the new API if you are used DataTables 1.10 or newer.
