Deprecate data_extract_spec

After release we need to deprecate `data_extract_spec` and replace it with `teal_transform_module`. This is extensive change.

- In `teal.modules.*` make `select_spec` or `choices selected` as a default argument (need a research which way to go).
- Then replace `data_extract_module` with ui elements specified directly.
- We need a simpler merge_module to consume information from inputs
- Make a function in teal which reads `server_args` and fetches and removes all `filter_spec` (from `data_extract_spec`). This should throw deprecation message and suggesting specifying `teal_transfrom_module`. This function except throwing errors should make a module based on the specifying `filter_spec` (this will be an automatic way of transforming filter_spec into `teal_transform_module`)
