Code Issues Proposed changes

Add certificate injection support to images

Browse Source 
This change adds support for injecting certificates into Docker images
during the build process using the same setup as airshipctl. Some proxy
servers use custom certificates, and those must be trusted by the
container.

# Additional Docker image root certificate authorities
If you require additional certificate authorities for your Docker image:
* Add ASCII PEM encoded .crt files to this directory
* The files will be copied into your docker image at build time.
To update manually copy the `.crt` files to `/usr/local/share/ca-certificates/`
and run `sudo update-ca-certificates`.
