User story

• As a funder I want to monitor a project in progress to decide on additional funding or dispute

Implementation

Specify use of milestones and potential use of Milestones plugin.

• Would conditional funding be pledged, meeting, allowing only to withdraw when meeting milestones? (partial withdraw: https://github.com/status-im/liquid-funding/issues/81)
• Who or what would review whether milestones are met?
