client: add support for pre-schema servers

Bundle remote plugin interface definitions for servers which lack API
schema support. These server API versions are included:
* 2.49: IPA 3.1.0 on RHEL/CentOS 6.5+,
* 2.114: IPA 4.1.4 on Fedora 22,
* 2.156: IPA 4.2.0 on RHEL/CentOS 7.2 and IPA 4.2.4 on Fedora 23,
* 2.164: IPA 4.3.1 on Fedora 23.

For servers with other API versions, the closest lower API version is used.

+Ping the remote IPA server to ensure it is running.
+
+The ping command sends an echo request to an IPA server. The server
+returns its version information. This is used by an IPA client
+to confirm that the server is available and accepting requests.
+
+The server from xmlrpc_uri in /etc/ipa/default.conf is contacted first.
+If it does not respond then the client will contact any servers defined
+by ldap SRV records in DNS.
