Load All projects

[sctsui]

Loading all projects saved by the user is currently only partially implemented. Progress is blocked by the broker's listKeys() method not listing the keys of prefix '/config/generator/v1/projects/' in etcd. ListValues() works, given the correct key.

Relevant code can be found in
https://github.com/sctsui/osseus/blob/feature/loadAll/plugins/restapi/handlers.go
method getAlProjects() (line 308)
Frontend recieving allProjects json will be done in line 77-79 of client/server.js
