Camel 4.4 - Add button to update route from XML

[davsclaus]

https://issues.apache.org/jira/browse/CAMEL-20274

We could do this in the past, but was removed due to enabled always. Now we have added it back, but with an option that end user must enable to have it supported.

You can check the JMX attribute if its enabled or not: isUpdateRouteEnabled
And if enabled then invoke updateRouteFromXml(xml) with the source from the text field.

Nice! @lhein so updating Camel routes can be restored.

[lhein]

Nice. We just need to ensure that this operation cannot be invoked by anybody as it is quite risky to change running integrations. WDYT?

[davsclaus]

Yes its disabled by default, but there is an option to enable it (such as for development) and jbang is enabled OOTB

@mmelko Could you work on it next?
