Allow Wildcards or 'All Tables' specification when adding Data Sources

[hennlo]

Affected Areas

DB, UI

Feature Description

When adding new Data Sources we currently only have the option to add tables, views by explicitly adding them name by name.

However, for larger projects this is impractical and tedious.
Instead allow adding multiple tables by creating a FLAG to add all tables
or allow wildcard specification using an asterix * to add all tables this user has access to for each schema.

This could also allow "blacklisting" some tables that should explicitly not be added.

Use Case(s)

This is related to Bug: #447
Intuitively it should work to add multiple tables at once , without specifying them one by one.

Possible Solutions

Extend SQL Syntax for system management to allow wildcards instead of specifying table by table.
Add possibility in UI to retrieve multiple tables at once. via wildcard or FLAG

Possible Alternatives

Add Data Sources only as connection objects and then in a separate step, create virtual/remote entities referencing to a source table via that connection.

That decouples the source creation from the virtual table creation.

This would also simplify "refreshing" definitions of existing data sources without really recreating them.

@hennlo is the expected result is to prevent user to input * right?

[hennlo]

@EslamAsHhraf No actually what you're describing is another issue: #447 that shall prevent any * from beeing rendered and executed because it currently breaks the schema.

This is issue is the successor to the first issue if you will so.
Becaase at the end I want to add different tables all at once without having to specify each one individually.
This issue is a little bit more advanced compared to the first one, because you need to add functionality to read the schema, detect all possibilities and subsequently add them to Polypheny.

But again if you want to work on prohibitting users to input * #447 is the issue for you.
