Merge ~leniwcowaty/curtin:lvm-stripes-handler into ~curtin-dev/curtin:master

[Leniwcowaty]

This fix enables setting up LVM striped volumes using curtin installer

This fix adds "stripes" key to validated schemas for LVM_PARTITION of type "integer".
It also adds handling of this key to the function lvm_partition_handler for block_meta to extend the command creating LVM volume with -i (--stripes) whenever stripes number is provided, is greater or equal to 2 and the number of stripes is even (a basic data sanitization).
