EXD: exacli setup

To configure exacli on EXD cells, create the following myadmin user on each cell as follow, using cellcli:

create role administrator;
grant privilege all actions on all objects all attributes with all options to role administrator;
create user myadmin password=*;
grant role administrator to user myadmin

Assuming as ssh equivalence exists between the compute node and these cells, exacli can be tested as follow, from any of the compute:

# exacli -l myadmin -c <cellname>
