Remove limitations on write operations for external tools

[Didier_TERRIEN]

Power BI External tools are limited when they write into the desktop's model : https://docs.microsoft.com/en-us/power-bi/transform-model/desktop-external-tools#supported-write-operations Please remove these limitations so the desktop reflects modification made in Tabular Editor

[fbcideas_migusr]

The current workaround to add or remove tables is way to complicated, please remove this last limitation.

Workaround:

1. In TE: Connect to local model
2. In TE: Save and reopen model locally
3. In PBI Desktop: save as pbip
4. In file explorer: replace model.bim in pbip
5. Reopen pbip
