Deploy on save exclusions

[robert-strunk]

Is your feature request related to a problem? Please describe.
I have Deploy on Save enabled. When I am working on LWC unit tests, each save triggers a failing push/deploy. Its a bit distracting.

Describe the solution you'd like
There may already be some mechanism to prevent that from happening but I wasn't able to find anything. I think a solid solution would be to create a new setting that allows you to specify directories that should not be included in the deploy on save functionality (similar to how a .forceignore ignores directories/files on push/pull/status)

Describe alternatives you've considered
Disabling deploy on save. I've also looked for existing settings/mechanisms that may address this issue.

I have this problem too.

I thought that .forceignore entries would be respected by the extension too.
