Commit 5bd60a745de22 ("Add telegraf agent (experimentally)") added the agent to
the rolling ISO. The telegraf daemon was thus always started by default and
simply consuming RAM without doing anything useful.
As all VyOS servcies are disabled by default, so is telegraf. If you wan't to
experiment with it, you can simply start and enable the service on your
system by:
systemctl enable telegraf.service
systemctl start telegraf.service
This is the completing commit for [1]. Moving this dependency here eases
development on the 5.9 Kernel tree and also on the ARM tree as now vyos-build
decides if an out-of-tree WireGuard modules should be incorporated into
the image or not.

This reverts commit 78c43c2078e292ac9b53d2d6a41a47466d283914.
Unfortunately we must revert the Kernel upgrade as there are two problematic
issues. One which is the break of ABI functionality with parted [1] and second
the internal cryptop API [2] which removed required literals for the build of
Intel QAT acceleration.
In the two weeks running 5.8 we still learned a lot - we experienced a
performance improvement of ~30% when doing NAT @ > 10GBit/s and also utilizing
the build in updated drivers for Intel NICs and WireGuard.
We are looking forward to the release of this years LTS kernel and we hope to
ship this in the final 1.3 release.

Note: Intel does not provide a compatible QAT version. There is a custom patch
which make QAT compile for the specified Kernel version. This patch will change
the source to a non backwards-compatible version - this is fine as we run 5.8
anyways.
