in some places in the code, there is a periodic task needs to be executed and the code is using time.sleep which is a bad practice.
for example, time.sleep may cause delays when receiving SIGTERM - if the go routine started the sleep section we will need to wait until sleep competes and only then the go routine will exist (due to context close).

the Go way for doing periodic task endlessly (until a cancel/close is received) is by using ticker.
