What

Add a "ignore_ssl" variable in digger-installer so it will add flags or ignore ssl checks when applicable.

Why

We have some issues around self signed cert with openshift and jenkins-cli when running it in a local developer machine which is not good for community members who want to try the project out.

How

• ansible "get_url" module and its siblings should set the "validate_certs" property (default being true).
• jenkins-cli should add the "-noCertificateCheck" command flag
• anything else?
