Add Agola Manager cli commands

[Alessandro Pinna]

Currently the /import, /export and /maintenance api are implemented by Runservice and Configstore.
I would like add cli commands to call this apis

I think the best way is to add a new agolamanager package because we don't need some agola flags, for example --gateway-url and --token

@alessandro-sorint These are temporary api that should be removed and implemented in a better way. It'll depend on the work I'm doing on removing the datamanager and etcd. So hold on.

It'll be better to use the same command and don't make these options global.
