Export more instance information in hooks
Currently we miss in hooks the instance's hypervisor, hypervisor
parameters and backend parameters. This forces hooks to query back into
ganeti, which is dangerous due to possible luxi sockets exhaustion.
This patch adds these three as INSTANCE_HYPERVISOR, INSTANCE_HV_*,
INSTANCE_BE_*. The hook environment prefixes all keys with “GANETI”, so
a default settings for a xen-pvm instance would be:
GANETI_INSTANCE_HV_initrd_path=
GANETI_INSTANCE_HV_kernel_args=ro
GANETI_INSTANCE_HV_kernel_path=/boot/vmlinuz-2.6-xenU
GANETI_INSTANCE_HV_root_path=/dev/sda1
Any dashes in parameter names are changed to underscores, since
variables with dashes are not easy to access from the shell
(alternatively we could deny those via an unittest for constants.py).
