  Log Message:
  -----------
  vtep-ctl: Exit if database connection fails.

Before this commit vtep-ctl hung forever if it didn't manage to reach
the database.

This caused the testcase "ovn -- 3 HVs, 1 VIFs/HV, 1 GW, 1 LS" to hang
occasionally, because ovsdb-server could be killed before ovs-vtep
called vtep-ctl.

This mimics the behaviour of ovs-vsctl, ovn-nbctl and ovn-sbctl.
