Description

This PR stops ignoring errors when setting resource data within the connection.

            * options.0.password_dictionary: '': source data must be an array or slice, got map
            * options.0.password_history: '': source data must be an array or slice, got map

        Error: 400 Bad Request: options.set_user_root_attributes can be set only for enterprise connections, social connections or custom database connections (using external users store)

Ultimately fixing these fixes several issues we have on github:

• Missing options when importing a connection object #33
• panic while using new version of provider #30
• Unsupported Connection Strategy ADFS #26
• auth0_connection 400 Bad request for google-apps strategy #23
• Add more logging for connection issues #21
• Unmarshal error when destroying auth0_connection resources #19
• Optional value in auth0_connection password_history setting #82

Adding a few comments to aid with reviewing.

[sergiught]

The issue here is that we define all possible parameters of the options object for all the different connection types and with the legacy SDK (v1) if we don't set something up for a TypeSet initially it will be read as "" but then after a state update it will be automatically set to an empty []string making the tests fail cuz there's an unexpected plan change. To fix this we need to set computed on this property and several others.

[sergiught]

This is actually not allowed and it was never set within the flatten for the Auth0 connection type. This property only works for enterprise connections.

The default by the API is to set brute force conection as enabled. Like this we remove the hack we introduced here https://github.com/auth0/terraform-provider-auth0/pull/97/files#diff-f2cec8e18d10bdff521bfda90a79b3154d267cccd5925b7ec9393cf7eeec7726L662-L666

This now allows to have a connection without options block defined in the terraform config.
