version: bump to 1.0.5

This is a breaking change!
Changes the id for configurations with a key algorithm set, which by default results in changes to serveral dependent configuration values as well,
such as cert_file/key_file/csr_file. This will require existing ECC setups to append the ecc suffix to files in the acertmgr configuration directory
