Exclude ESM from apt:sources for development-vm
Exclude ESM from apt:sources for development-vm

- ESM for extended Ubuntu Trusty support was recently added as Trusty is EOL
and support by Canonical is now paid-for
- We cannot currently add the Canonical credetials for ESM access to the
development-vm as our support contract is per machine.
- This caused Puppet errors on development-vm deployment
- Decision: Simply remove ESM repos from development-vm hieradata
