[Buildroot] [PATCH 0/2] package/python-scp: new package

[Alexis Lothoré via buildroot]

Hello,
this small series adds support for the small python-scp package, which
comes on top of the paramiko python package to ease download/upload of
files thanks to SCP protocol.

- Patch 1 brings the new package. It is mostly based on ./utils/scanpypi
  scp -o package
- Patch 2 brings a small test ensuring that python-scp is properly
  installed and is usable

Add python-scp as a new package. python-scp allows to send and receives
files in python through the scp1 protocol, on top of paramiko.

Series applied to master, thanks.

For info, I did few minor changes to the runtime test. See:
https://gitlab.com/buildroot.org/buildroot/-/commit/7470587cfa9a24d3c49adc0fb6cc60512907f31a

[Buildroot] [PATCH 2/2] support/testing: add runtime tests for python-scp

[Alexis Lothoré via buildroot]

Add a basic test involving a local SSH connection (based on dropbear
server). The test validates that we are able, through python-scp, to
fetch the /etc/hostname file.

The test needs some basic key initialization to allow connecting to the
dropbear server, hence the custom run_sample_scripts method.
