MongoDB: SSL certificate

As of November 2020 (F20) and continuing into February 2021 (W21), developers working with Spring Boot and MongoDB on MacOS are running into this error when connecting to a MongoDB database:

2021-02-02 13:13:04.364  INFO 65733 --- [ngodb.net:27017] org.mongodb.driver.cluster               : 
Exception in monitor thread while connecting to server cluster0-shard-00-02.l6wrx.mongodb.net:27017

com.mongodb.MongoSocketWriteException: Exception sending message
	at com.mongodb.internal.connection.InternalStreamConnection.translateWriteException(InternalStreamConnection.java:551) ~[mongodb-driver-core-3.11.2.jar:na]
	... [ many stack frames omitted ]

Caused by: javax.net.ssl.SSLHandshakeException: extension (5) should not be presented in certificate_request
	at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:131) ~[na:na]

The following work around seems to fix this:

Add the flag -Dspring-boot.run.jvmArguments="-Djdk.tls.client.protocols=TLSv1.2" when running the mvn spring-boot:run command, like this:
```
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Djdk.tls.client.protocols=TLSv1.2"
```
