Make `cscli hubtest -appsec` troubleshooting easier

[buixor]

What would you like to be added?

Indicate the user if nginx isn't running

If one forgot to start the docker-compose to have nginx running, the error message is a bit cryptic:

 cscli --appsec run vpatch-CVE-2021-44529 --report-success
Error: unknown command "vpatch-CVE-2021-44529" for "cscli"
root@zeroed:/home/bui/github/crowdsec/hub# cscli hubtest --appsec run vpatch-CVE-2021-44529 --report-success
INFO Appsec tests can not run in parallel: setting max_jobs=1 
Running test 'vpatch-CVE-2021-44529'
Error: target is down: took more than 10s for 127.0.0.1:7822 to be available

We could point the user towards the fact that we didn't manage to reach nginx

Point out to the user if nuclei didn't run

If the user has an error in his nuclei template, no request will be made to the nginx server, making it harder to debug. We could display nuclei stderr/stdout to the user when it returns an error to provide some hints:

[INF] Current nuclei version: v3.1.7 (outdated)
[INF] Current nuclei-templates version: v10.1.6 (latest)
[WRN] Scan results upload to cloud is disabled.
[INF] New templates added in latest release: 78
[INF] Templates loaded for current scan: 1
[WRN] Executing 1 unsigned templates. Use with caution.
[INF] Targets loaded for current scan: 1
[WRN] [CVE-2024-3400] Could not execute request for http://127.0.0.1:7822/: net/http: invalid header field name "user=global&portal=global&authcookie=e51140e4-4ee3-4ced-9373-96160d68&domain=global&computer=global&client-ip=global&client-ipv6=global&md5-sum=global&gwHipReportCheck=global"
[INF] No results found. Better luck next time!
