ClassNotFoundException for SQL query

[neilstevenson]

Describe the bug
An exception is thrown if an SQL query is run against a map containing custom classes.

Tested using 5.2.0-SNAPSHOT

Encountered an unexpected exception while executing the query:
Failed to deserialize query result value: java.lang.ClassNotFoundException: hazelcast.platform.demos.banking.trademonitor.NasdaqFinancialStatus
com.hazelcast.nio.serialization.HazelcastSerializationException: Failed to deserialize query result value: java.lang.ClassNotFoundException: hazelcast.platform.demos.banking.trademonitor.NasdaqFinancialStatus

Expected behavior
No exception to be thrown

To Reproduce
Create a custom class - eg. https://github.com/hazelcast/hazelcast-platform-demos/blob/master/banking/trade-monitor/custom-classes/src/main/java/hazelcast/platform/demos/banking/trademonitor/SymbolInfo.java
Insert it into a map
Run SELECT * FROM map from hz-cli

Additional context
Superficially this is user-error. The classes aren't on the classpath of hz-cli.

However, since the SQL runs serverside and returns standard columns - text and numerics - deserialization should run serverside (which has the classes).
