Add TLS support to artemis scaler

[sambou90]

Proposal

It looks like the ActiveMQ Artemis scaler does not support TLS. The http:// is hardcoded in the constant value defaultRestAPITemplate: https://github.com/kedacore/keda/blob/main/pkg/scalers/artemis_scaler.go#L52

It would be nice if there is the same possibility like in the ActiveMQ Scaler: https://github.com/kedacore/keda/blob/main/pkg/scalers/activemq_scaler.go#L50

Otherwise it seems like it is not possible to use TLS for secure connection.

Use-Case

Use scaler ActiveMQ Artemis with TLS for secure connection.

Is this a feature you are interested in implementing yourself?

Maybe

Anything else?
