Improve bsconfig.json auto-discovery

[elsassph]

Problems

There are issues with bsconfig.json auto-discovery:

• Language server may crash with large monorepos making use of symlinks; implementation uses rokuDeploy.getFilePaths which is quite inefficient for our need,
• bsconfig.json are looked into Search-excluded locations.

Changes

• replaces rokuDeploy.getFilePaths with a direct fastGlob call with followSymbolicLinks disabled,
• add Search exclude to the filters

Behaviour change

Some users may rely on symlinks or search-hidden locations; this can be worked around by adding manually folders in the Workspace.

Looks good! Can you fix the failing test?
