there are schema changes when upgrading from 1.0.3 to 1.0.4 but not when upgrading to 1.1.0.
These scripts are called when 'yum upgrade HIRS_AttestationCA' is invoked.
Fixed script file path
Fixed MySQL syntax error
These changes now differentiate between upgrade versions and add respective columns, and also
account for upgrades from 1.0.3 directly to 1.1.0.
