Remove agent vendor passthru from most drivers

This patch removes the deprecated agent lookup/heartbeat as vendor passthru functionality from most of the drivers in following modules: - ironic.drivers.agent - ironic.drivers.pxe - ironic.drivers.drac - ironic.drivers.irmc Some drivers are left untouched though: - iLO and OneView drivers are a bit more complicated and will be fixed in follow-up patches - iBoot, WoL and AMT drivers will be fixed in ironic-staging-drivers repo first and then removed from ironic tree. Change-Id: Ia9ee46cda68ef823d1fe8e5ea03c1d5948810a50 Partial-Bug: #1640533

+    Agent lookup/heartbeat as vendor passthru is removed from most of
+    in-tree ironic drivers. Affected drivers are
+
+    * agent_ipmitool
+    * agent_ipmitool_socat
+    * agent_ipminative
+    * agent_irmc
+    * agent_ssh
+    * agent_vbox
+    * agent_ucs
+    * pxe_agent_cimc
+    * pxe_ipmitool
+    * pxe_ipmitool_socat
+    * pxe_ssh
+    * pxe_ipminative
+    * pxe_seamicro
+    * pxe_snmp
+    * pxe_irmc
+    * pxe_vbox
+    * pxe_msftocs
+    * pxe_ucs
+    * pxe_iscsi_cimc
+    * pxe_drac
+    * pxe_drac_inspector
+    * iscsi_irmc
+
+    All the other vendor passthru methods are left in place if the
+    driver had them.
+upgrade:
+  - Agent lookup/heartbeat as vendor passthru is removed from ironic.
+    That means that most in-tree drivers relying on Ironic Python Agent (IPA)
+    lookup/heartbeat functionality become incompatible with IPA < 1.5.0.
+    Operators are required to update their IPA-based deploy ramdisks to
+    contain IPA >= 1.5.0.
