* luks_device: allow passphrases to contain newlines
This is useful when passing binary keyfiles from an ansible vault, as
it removes the restriction that the binary data cannot contain newlines.
The only exception is adding a new key to an existing container, as in
that case the two passphrases are separated by a new line.
* add integration tests and a changelog fragment
* attempt to also make luks_add_key work with passphrases containing
newlines
* use a deterministic method to generate keyfile 3, improve changelog
formatting
* add licence and copyright to keyfile3.txt to satisfy CI
* luks_device: fix remove_keyslot not working when set to 0
* luks_device: fix module outputting 'ok' when trying to add a key that is already present in another keyslot
* luks_device: fix breaking unit tests
* luks_device: Duplicate key test case code cleanup
* luks_device: Fix testing of LUKS passphrases when only testing one key slot
* luks_device: Fix testing of LUKS passphrases when only testing one key slot
* luks_device: Add changelog fragment for PR #710
* luks_device: Update changlog fragment
* add allow discard option for luks devices
* Add allow_discards to perfomance tests
* Fix version for luks devices doc
* Update plugins/modules/luks_device.py

Read and write work queue significantly degrades performance on
SSD/NVME devices[1].
In Debian 11 crypttab does not support no-read-workqueue and
no-write-workqueue flags, so the persistent flag is workaround: once
opened with perf parameters persists forever.
