Use case-insensitive comparison for jenkins job names

[slopes321]

When deciding whether a job already exists on jenkins, or whether a new job needs to be created, the jenkins_pipeline_builder does a case-sensitive search; i.e. MyJob and MYJOB are considered to be different jobs. If the builder finds MYJOB on jenkins and it is processing MyJob, it will attempt to create a new item.

However, Jenkins will treat MyJob and MYJOB as a name collision, and the creation of MyJob will fail with JenkinsApi::Exceptions::JobAlreadyExists.

The builder should use the same case-insensitive comparison used by Jenkins to avoid this.
