Remove unnecessary security-server files

Remove unnecessary security-server files

This commit starts a fork from security-server repository,
that initially security-manager was part of.
All parts of security-server that was not needed by security-manager
are removed. That means removing security-server-client
and removing all services exept security-manager's ones.
