Subject: Use Apache Activemq as a broker to communicate with esp32 via MQTT

Problem Description

Example: ssl_mutual_auth, the broker is mosquitto,and generate key and csr
in .pem format using OpenSSL.

Finally use Mosquitto test certificate signer to get the client certificate
and put the certificate into the program.

Now I have an Apache ActiveMQ 5.15.9 broker server, I want my esp32 through
ssl-mutual-auth for MQTT communication.

However, the information like this CSDN blog or The Apache Tomcat I found
on the Internet shows that the Apache Activemq server uses keytool to
generate .keystore and .truststore files that are not .pem format files
for ssl verification.
