Ensures bootloader_disks is set to one type to keep
index generation bound to one falvor type. Shifts generate
disk loop to use bootloader_flavors variable taht can be stacked
with multiple types.
Should fix issue causing the index to have the last name in the list
of bootloader_disks which was setting the incorrect name. This was
probably introduced with the change in:
https://github.com/netbootxyz/netboot.xyz/pull/1096
* Shifting after_deploy messages and aws invalidation to
proper locations
* Add cert checkout to preinstall and setting those on s3
deploys only
* Adding production docker file which runs netboot.xyz overrides
* Only display sig menus if enabled
* Fix var names for signing
* Adds ability for self hosted custom menus
Templates can be added to /etc/netbootxyz/custom and are
generated and placed in the custom directory of the root
web directory by setting custom_generate_menus to true.
This provides an option on the main netboot.xyz menu to chain
into a custom environment so that seperate local menus can be
added and maintained seperately from the netboot.xyz source
code tree.
* Remove todo
