get rid of CryptographyDeprecationWarning

[fruch]

in recent updates to the hydra docker image, we start getting those warnings

/usr/local/lib/python3.10/site-packages/paramiko/pkey.py:100: CryptographyDeprecationWarning: TripleDES has been moved to cryptography.hazmat.decrepit.ciphers.algorithms.TripleDES and will be removed from this module in 48.0.0.
  "cipher": algorithms.TripleDES,
/usr/local/lib/python3.10/site-packages/paramiko/transport.py:259: CryptographyDeprecationWarning: TripleDES has been moved to cryptography.hazmat.decrepit.ciphers.algorithms.TripleDES and will be removed from this module in 48.0.0.
  "class": algorithms.TripleDES,

we should see if upgrade of paramiko can help, or add a way to quiet those for now

[fruch]

there an ongoing talk about it in:
paramiko/paramiko#2419

and PR with suggested fix

so we can wait for next release of paramiko, and pick it up
