Refactor kubectl retrieve logs test to use agnhost

Browse Source 
Windows is having trouble running this test because the Redis
port for Windows is older than the one used by the test, as
described in the issue #80265.

Changing the "Kubectl should retrieve and filter logs" test
to use the agnhost image to generate the logs.

Release : v1.9
Testname: Kubectl, logs
Description: When a Pod is running then it MUST generate logs.
Starting a Pod should have a log line indicating the server is running and ready to accept connections. Also log command options MUST work as expected and described below.
Starting a Pod should have a expected log line. Also log command options MUST work as expected and described below.
‘kubectl log -tail=1’ should generate a output of one line, the last line in the log.
‘kubectl --limit-bytes=1’ should generate a single byte output.
‘kubectl --tail=1 --timestamp should generate one line with timestamp in RFC3339 format
