asclepios: assumes that it can connect via a normal user account

[lnussbaum]

I test asclepios using the 'min' environment. However it seems that the code assumes that it is able to connect using my normal user account, instead of the root account:

2015-06-09 14:24:48,781 DEBUG: 7/8 processes terminated in <Get([Host(u'econome-2.nantes.grid5000.fr'), Host(u'econome-3.nantes.grid5000.fr'), Host(u'econome-10.nantes.grid5000.fr'), Host(u'econome-12.nantes.grid5000.fr'), Host(u'econome-13.nantes.grid5000.fr'), Host(u'econome-14.nantes.grid5000.fr'), Host(u'econome-16.nantes.grid5000.fr'), Host(u'econome-17.nantes.grid5000.fr')], ['/tmp/lshw/{{shosts}}.xml'], local_location='econome_20150609_142447_+0200/lshw/')>

ok, this is caused by me using --nodeploy. It would still make sense to provide a way to supply the username

I have added a --user option.
But I have some question regarding the general workflow.
