[pgpool-committers: 5065] pgpool: Use failover instead of fail-over pr fail_over

[Muhammad Usama]

Use failover instead of fail-over pr fail_over

Fix mistakes where "fail_over" and "fail-over" were used instead of the
"failover". And that also includes a wrongly spelled configuration parameter
"fail_over_on_backend_error",
Now we throw a warning message when old config name fail_over_on_backend_error
is used instead of failover_on_backend_error,
Using the old config variable name will have no effect.
