BLISS has a motor controller exporting axes from ESRF insertion devices.
* `ds_name` has to be the fully qualified name of the corresponding Tango server.
* `period`: period in mm of the undulator. Read from config (Usually the number
in undulator name)
* `alpha`: alpha is a magic parameter used for undulator calibration. Read from
config (To be set by BL staff or undulator group member)

For each axis the corresponding Tango attribute names for position,
For each axis, the corresponding Tango attribute names for position,
velocity and acceleration have to be specified.
!!!note
`ESRF_Undulator` controller is a `NoSettingsAxis`, i.e. the parameters
like velocity, accelerations are not configured in Beacon but read from Tango DS.
There are 2 ways to do that:
