Use Python-3 compatible syntax, without breaking compatibility with py 2.7

- Octals literals start with 0o to prevent confusion
- The "L" at the end of large int literals is not required as they use
  long on Python 2 automatically.
- Using 'int' instead of 'long' for small numbers is OK in all cases except
  strict type checking checking, e.g. type(0).

* Remove NSEC3, DNSKEY, TSIG, TKEY, TA records from API:
    These records never worked, they dont have attributes in schema.
    TSIG and TKEY are meta-RR should not be in LDAP
    TA is not supported by BIND
    NSEC3, DNSKEY are DNSSEC records generated by BIND, should not be
    in LDAP.
    *! SIG, NSEC are already defined in schema, must stay in API.

* Add HINFO, MINFO, MD, NXT records to API as unsupported records
    These records are already defined in LDAP schema

* Add schema for RP, APL, IPSEC, DHCID, HIP, SPF records
    These records were defined in IPA API as unsupported, but schema definition was
    missing. This causes that ACI cannot be created for these records
    and dnszone-find failed. (#5055)

The vault plugin has been modified to support symmetric and asymmetric
vaults to provide additional security over the standard vault by
encrypting the data before it's sent to the server. The encryption
functionality is implemented using the python-cryptography library.

Add integration of python-kdcproxy into FreeIPA to support the MS
Kerberos KDC proxy protocol (MS-KKDCP), to allow KDC and KPASSWD
client requests over HTTP and HTTPS.

- freeipa-server now depends on python-kdcproxy >= 0.3. All kdcproxy
  dependencies are already satisfied.
- The service's state is configured in cn=KDC,cn=$FQDN,cn=masters,cn=ipa,
  cn=etc,$SUFFIX. It's enabled, when ipaConfigString=kdcProxyEnabled is
  present.
- The installers and update create a new Apache config file
  /etc/ipa/kdcproxy/ipa-kdc-proxy.conf that mounts a WSGI app on
  /KdcProxy. The app is run inside its own WSGI daemon group with
  a different uid and gid than the webui.
- A ExecStartPre script in httpd.service symlinks the config file to
  /etc/httpd/conf.d/ iff ipaConfigString=kdcProxyEnabled is present.
- The httpd.service also sets KDCPROXY_CONFIG=/etc/ipa/kdcproxy.conf,
  so that an existing config is not used. SetEnv from Apache config does
  not work here, because it doesn't set an OS env var.
- python-kdcproxy is configured to *not* use DNS SRV lookups. The
  location of KDC and KPASSWD servers are read from /etc/krb5.conf.
- The state of the service can be modified with two ldif files for
  ipa-ldap-updater. No CLI script is offered yet.
