make heart beat log less verbose

[nurali-techie]

Issue:
Currently, every loop_wait iteration, 2 info log entry added to master node and 3 info log entry added to replica node.

Details:
Below 2 info log entry added to master node:

2020-08-27 05:55:07,591 INFO: Lock owner: patroni1; I am patroni1
2020-08-27 05:55:07,598 INFO: no action.  i am the leader with the lock

Below 3 info log entry added to replica node:

2020-08-27 05:55:49,603 INFO: Lock owner: patroni1; I am patroni2
2020-08-27 05:55:49,603 INFO: does not have lock
2020-08-27 05:55:49,609 INFO: no action.  i am a secondary and i am following a leader

Expectation:
Ask is to make 1 info log entry for both master and replica.

Benefit:
With 1 info log entry there will be less log generated. Also, with 1 log entry, there will be pattern when you see log file and if there is something else is added to log then you can find odd man out very easily.

Thanks @CyberDem0n ; for now let's close this. I will plan to do it soon and at that time I will ask more details on new log entry text etc. 👍
