Introduce plugin logpersister package

[khanhtc1202]

What this PR does:

Introduce plugin logpsersister package

Why we need it:

In pipedv0, we use logPersister as the writer for stage logs (which will later be used to show stage logs on UI). In this PR, I created pkg/plugin/logpersister package, with the same responsibility, but instead of sending the stage log directly to the controlplane, it sends to piped plugin-api then piped will send it to the controlplane.

Which issue(s) this PR fixes:

Part of #4980
