There was no way to setup correct repo when AMI is building by --localrpm option, since AMI does not have access to 'version' file, and we don't passed repo URL to the AMI.
So detect optimal repo path when starting build AMI, passes repo URL to the AMI, setup it correctly.
Note: this changes behavor of build_ami.sh/scylla_install_pkg's --repo option.
It was repository URL, but now become .repo/.list file URL.
This is optimal for the distribution which requires 3rdparty packages to install scylla, like CentOS7.
Existing shell scripts which invoking build_ami.sh are need to change in new way, such as our Jenkins jobs.
