Allow reader retry if acquisition file read fails

[rr404]

/kind enhancement

What would you like to be added?

Context: Runnin crowdsec as non-root on Cloudways
Issue: "randomly" when log rotate, reader doesn't seem to have permission to read newly created file (maybe some weird race condition). It can work 3 days and crash the 4th or crash on first rotation, it seems random.
I assume it's because we're not root that this happens, but maybe there are other cases where log reader fails this way

Error:My crowdsec logs show this (I obfuscated the path):

time="2024-09-18T00:00:50Z" level=info msg="Re-opening moved/deleted file /<absolute_path>/nginx_wordpress-11111-11111.cloudwaysapps.com.access.log ..."

time="2024-09-18T00:00:50Z" level=warning msg="file reader of //<absolute_path>/nginx_wordpress-11111-11111.cloudwaysapps.com.access.log died : Unable to open file /<absolute_path>/nginx_wordpress-11111-11111.cloudwaysapps.com.access.log: open /<absolute_path>/nginx_wordpress-11111-11111.cloudwaysapps.com.access.log: permission denied" tail=/<absolute_path>/nginx_wordpress-11111-11111.cloudwaysapps.com.access.log type=file

Feature: Could we have a config to say that a reader retries like N times every X seconds if fails to read a rotating log ?

Why is this needed?

Be able to run CrowdSec on CloudWays managed servers (where we don't have root privileges)
