Modified the startup to collect some telemetry data and send to a cloud collector

[andsel]

During startup are collected:

• OS
• cpu arch
• jvm version
• jvm vendor
• max heap (Xmx)
• broker's version
• uuid for the boker instance

and sent to a telemetry collector to understand how Moquette is used in the wild and provide some better features.

This functionality is enabled by default, but can always by disabled by setting

telemetry_enabled false

in the config file or passing config properties with

configProps.setProperty(BrokerConstants.ENABLE_TELEMETRY_NAME, "false");

when launching in embedded mode.
