krb5 commit: Use context profile for libkadm5 configuration

https://github.com/krb5/krb5/commit/49a857808b918440793daa81c8fe352326623fef
commit 49a857808b918440793daa81c8fe352326623fef
Author: Greg Hudson <[email protected]>
Date:   Mon May 9 10:41:47 2022 -0400

    Use context profile for libkadm5 configuration
    
    In kadm5_get_config_params(), uxe the context profile instead of
    creating a new one with krb5_aprof_init().
    
    In kproplog, obtain the context with kadm5_init_krb5_context() so that
    KDC configuration is used.
    
    ticket: 9059 (new)
