Fixing broken encryption support in GRUB (#724)

* Added multiple `partprobe` calls and added a `.partprobe()` function on partitions, filesystem and blockdevice.
* Adding retry attempts to all UUID related operations tied to the boot process
* Tweaked logging for mounting and disk related operations
* Removed potential SysCall exception disruptor causing exceptions to go by unnoticed
* Increased the start position from 1MiB to 5MiB of /boot partition
* Optimized the GRUB installation & config code
* Improved Partition().uuid to never return None. Instead it will raise an exception if it can't get a PARTUUID within X retries with Y delay per attempt.
* Increased sleep timer for partition uuid retrieval, because even with a 3 second sleep it wasn't long enough even on fast devices.
* Make GRUB install to /dev/sda instead of /dev/sda1.
* Added 10 retries for retreiving PARTUUID with a one second sleep. Instead of increasing the sleep simply add more retries until we find a good balance on slower disks.
