Plugins Version

[ricardobur]

I am trying to specify the version of the plugins in my docker-compose.yml. I have tried to put it as as specified in grafana plugins docs but it has been impossible to install the required version. I think it could be fixed of the way that GF_INSTALL_PLUGINS is read, making possible to read the var with values like the next example:

GF_INSTALL_PLUGINS=grafana-piechart-panel 1.1.4,mtanda-histogram-panel 0.1.5

Would it be possible to add the possibility to add plugins version?

Should be fixed by #60
