Command Palette should be filterable/customized by user-settings

[defjosiah]

• VSCode Version: 1.19.0
• OS Version: High Sierra

Steps to Reproduce:

1. Open up user-setting, try to figure out how to filter the command palette
2. There is no option to filter the command palette

Reproduces without extensions: Yes

I'd like to be able to filter down the command palette to only show relevant commands (i.e. only show golang commands while I'm in a golang workspace). I think this can be achieved by adding context to commands (maybe similar to how keyboard shortcuts can be applied in certain language modes).
