Upgrade Karaf to the latest version [4.2.6] about ddf

[Kjames5269]

@coyotesqrl No they will not be because other contributors can't edit the description. I'm waiting on a PR to get merged to the 2.13.x branch that is a workaround. If that gets forward ported I'll put that PR here.

@Kjames5269 Are the workarounds you mentioned in Additional Information going to be added to the description?

[Kjames5269]

#4353 is a current workaround

[Kjames5269]

#4360

[Kjames5269]

#3763 will hopefully be fixed in the next version of Karaf but I don't believe is implemented in [4.2.3].

another 4.2.2 bug that would be resolved by upgrading https://issues.apache.org/jira/browse/KARAF-6076

This upgrade is ultimately blocked by this issue in Jetty :
eclipse/jetty.project#3466
While the fix has be added in 9.4.18.v20190429, Pax Web did not catch it until after 7.2.10 was released.

We were unable to force setting the endpointIdentificationAlgorithm inside of a config. As such, we will need to wait for a new release of Pax Web (7.2.11) to complete the upgrade.
