lvmd hardcodes binary paths, crashes in nixos

[mlazowik]

lvmd assumes that lvm is in /sbin/lvm, similarly with some other binaries. This is not true in e.g. nixos

Environments

• Version: ghcr.io/topolvm/topolvm-with-sidecar:0.29.0, chart 14.1.2
• OS: nixos

To Reproduce
Steps to reproduce the behavior:

1. Deploy lvmd as DaemonSet on k8s with nixos nodes
2. lvmd crashes with "failed to run command","error":"exit status 127: nsenter: failed to execute /sbin/lvm: No such file or directory"

Expected behavior
One option could be to provide binary path in config/cli arg.

Thank you for your report.
Your suggestion is valid. We'll fix it. Also, problems like those you filed can be raised on different host distributions which we don't use on CI, so we'll denote our testing distribution.
