…r#337)

Orca runs MonitorQueuedJenkinsJobTask until the number is not null and
then uses that in MonitorJenkinsJobTask. Returning the id in QueuedJob
results in the wrong number stored in the context and MonitorJenkinsJobTask
then gets 404s back from Jenkins.

* fix(jenkins): don't error out on queue item responses with missing field

We don't want to throw an NPE if there is no `executable` element in the
response. I noticed this element now seems to correspond to `id` so use
that as a fallback if we can.

* fix(jenkins): replace SimpleXML with Jackson for XML deserialization

I am now suspecting that SimpleXMLConverter is responsible for the leaked
connections. I haven't witnessed any leaked connections anymore after
switching to Jackson.

Switch from SimpleXML to mostly JAXB annotations, with a few Jackson
annotations when it seemed necessary (for unwrapped collections).

This is one step closer to moving off of SimpleXML (deprecated in retrofit2)
and should make it easier to switch serializations implementations in the
future.

It seems we can get undeterministic ordering of sibling which should not
be a big deal but breaks some unit tests that depend on an exact string
output, so only check the semantic values of the response, not the ordering of the
elements

fix(travis): grace period before triggering with new travis builds

* fix(travis): grace period before triggering with new travis builds

The travis api needs some time after a build is finished in order to have
the build data present in the apis.

* Make new build grace period configurable

* suffix with seconds

* add seconds to comment as well

feat(core): Apply artifact filtering in Igor (spinnaker#321)

* feat(core): Apply artifact filtering in Igor

BREAKING CHANGE: This is a breaking change for users who
have manually set BuildArtifactFilter.maxArtifacts or
BuildArtifactFilter.preferredArtifacts as environment variables
to Orca. As the filtering logic is being moved to Igor, these
environment variables need to be set on the Igor process. This
change will also cause the results of calling the Gate endpoint
"/v2/builds/..." to get build status to return a filtered list
of artifacts.

All current calls to get the build info for a particular build
post-process by filtering the artifacts with BuildArtifactFilter.
Rather than require all callers to post-process, move this logic
from Orca to Igor so that the API returns already-filtered
artifacts.
