Improve ability to triage errors

[yashbhutwala]

I tried this plugin and I see this error

kubectl logs -n XXX kubectl-flame-80bde19a-17e5-4a15-8aa0-edf8dce6c58c-sb2zb {"type":"progress","data":{"time":"2020-08-24T13:17:47.12752075Z","stage":"started"}} {"type":"error","data":{"reason":"exit status 1"}}

kubectl flame -n XXXX XXX-894cd9c96-452nl Verifying target pod ... ✔ Launching profiler ... ✔ Profiling ... Error: exit status 1

Getting a little bit more error, but still not anything triageable/actionable with v0.1.2.

> kc flame -n XXX XXXXX -t 1m -f /tmp/flamegraph.svg --alpine

This issue relates to #12

我也遇到了这个问题，我想应该是容器所运行的宿主机中没有安装linux-header-* 软件包导致的；对于golang进程使用bpf需要使用内核软件包，我想Flame插件程序也应该对于此问题有个更合适的解决方案
