Configure Password Hashing Algorithm

OpenDXP uses PHP's default password hashing algorithm by default, which currently equals to BCrypt with a cost of 10 (see PASSWORD_DEFAULT), but the algorithm can also be configured (see here for possible algorithms and their options), for example:

opendxp:
   security:
       password:
           algorithm: !php/const PASSWORD_BCRYPT
           options:
               cost: 13

This config will be used for OpenDXP's backend users and fields of type Password in custom OpenDXP Objects.
