The UI validation error messages are incorrect, or at least misleading

The subnet mask can't be lower than '/${AWS_MACHINE_CIDR_MIN}'.

Should be

The subnet mask can't be larger than '/${AWS_MACHINE_CIDR_MIN}'.

(CIDR notation can be confusing, smaller numbers indicate larger blocks of IPs)

Same logic follows with

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L470
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L474
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L491
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L497
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L512
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L525
  • higher -> smaller

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L660
  • lower -> larger

• https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L664
  • higher -> smaller

Finally, I believe the "which provides up to X nodes." logic in https://gitlab.cee.redhat.com/service/uhc-portal/-/blob/master/src/common/validators.js#L488-498 is wrong. I'm not sure what the proper validation is, but we should consider removing this part of the message until it's been properly vetted.
