params: list with the params to be sent to the VIM for CREATE or FIND. For DELETE the vim_id is taken from other related tasks
find: (only for CREATE tasks) if present it should FIND before creating and use if existing. Contains the FIND params
depends_on: list with the 'task_index'es of tasks that must be completed before. e.g. a vm creation depends on a net creation
+ can contain an int (single index on the same instance-action) or str (compete action ID)
sdn_net_id: used for net.
tries:
interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database
