    Fix tls-proxy on newer versions of openssl

    Newer versions of openssl (CentOS9Stream for example) do not like using sha1.
    Devstack will fail on these systems[1] with the following error:
    801B93DCE77F0000:error:03000098:digital envelope routines:do_sigver_init:invalid digest:crypto/evp/m_sigver.c:333:
    This patch updates the tls-proxy code in devstack to use sha256 instead of sha1 which allows devstack to complete when tls-proxy is enabled.
