Process to reset the elasticsearch user

**Open a bash shell inside elasticsearch docker container, and run this command:
(when prompted, set the user password)

bin/elasticsearch-reset-password --username elastic -i

Do the similar thing for kibana_system user

bin/elasticsearch-reset-password --username kibana_system -i

Once done, you are all set to log in inside the web UI on your http://localhost:5601.

The value for XPACK_ENCRYPTEDSAVEDOBJECTS_ENCRYPTIONKEY is generated by following these steps:

./bin/kibana-keystore create
./bin/kibana-keystore add elasticsearch.password

(here, elasticsearch.password is the password for user kibana_system)
