[Feature]: Filtering by environment type

Is your feature request related to a problem? Please describe.
Scalr has the Environment type feature and this filter is missing in the VScode extension.

Describe the solution you'd like
I'd like to have the environment types filter, where I can select a few types and then perform any action (if available).
