[FR]Normalize equity symbols

[yolotrader]

What's the problem of not having this feature?
Currently OpenBB relies on its data providers to resolve a symbol. Unfortunately providers format symbols slightly differently in certain cases. A typical example is that yfinance uses "BRK-A" for Berkshire A shares where as many others use the more common "BRK.A". This requires users to remember these subtleties and developers to write extra code to handle them.

Describe the solution you would like
It would be great if OpenBB can adopt a uniform convention for using "." in the symbol format and use the provider extensions to convert it to "-" (or some other character) as necessary. This will help both regular users and developers.

Describe alternatives you've considered
If there are other alternatives (worth considering) to your solution, list them here.

Would be worthwhile to integrate OpenFGI API.

Yes, however, it would be for a different purpose. OpenFIGI won't help with mapping between vendor's symbology, and especially where a ticker symbol is the only type of input allowed.

Is it BRK.A or BRK-A or BRK.A:US or BRK/A? Nuances there are very specific to vendors and most don't have handling for different formats.
