Diagnostic code shown in Problems view is unpleasant

[egamma]

Testing: microsoft/vscode#62092

See the screenshot below and notice:

• each tslint diagnostic has the same diagnostic code 10000
• each diagnostic includes the rule name

At some point it was discussed that error code are strings in the TS language service. If that would be the case then tslint could use the rule name as the diagnostic code

Same problem with diagnostic hover

Looks like TS currently only supports using number codes for diagnostics. Will sync with the TS team to see what we can do to improve the experience here

@mjbvz some cosmetic tuning would be to use a smaller number than 100000 for the tslint error code.
