Describe the problem you'd like to have solved

Users are unable to create a new address for a validator, neither in the CLI nor GUI application. The address new command in the CLI only creates an account address.

Describe the ideal solution

We should add a new optional flag, such as "--address_type," with values like "validator" or "bls_account." The default value should be set to "bls_account" for now.

Alternatives and current workarounds

Currently, there is no workaround available for this issue.

Please close this issue when both the CLI and GUI support creating a new address for validators.
