[MaaS] Force Maas to use a fixed ip packet size
Maas uses a tftp library during commisioning which in turn uses another
library which tries to find the best packet size to use. For some reason
during commisioning the library uses smaller sizes than the
infrastructure can handle and therefore takes a lot of time to deploy.
