DRBD: Add hmac/secret param support

DRBD has its own authentication mechanism between drbd nodes.
To enable DRBD peer authentication, we need to specify the
following two parameters.
- cram-hmac    : The HMAC algorithm to enable peer authentication
- shared-secret: The shared secret used in peer authentication
in drdb resource configuration to enable DRBD peer authentication.

This change adds the following 3 new parameters;
- hmac  : Represents cram-hmac
- secret: Represents shared-secret
- secure: Enable peer authentication (if this is false,
          cram-hmac is "sha1" and no shared-secret will be
          present in drbd resource configuration files)

Test Plan:
PASS: Confirm hmac and secret has proper values in drbd resource
      config when hmac and secret parameters are configured
PASS: Confirm drdb resource config has hmac default value and
      no secret when hmac and secret parameters are not configured.
PASS: SX fresh install finishes successfully. Confirm drdb resource
      config has proper hmac and secret values.
PASS: SX upgrade finishes successfully. Confirm drdb resource
      config does not have new hmac value nor secret.
PASS: DX fresh install finishes successfully. Confirm drdb resource
      config has proper hmac and secret values.
PASS: DX upgrade finishes successfully. Confirm drdb resource
      config does not have new hmac value nor secret.
