[Postgres-xc-developers] Pgxc_ctl fixes

[Koichi S. <koi...@gm...>]

The patch contains two fixes:

1. gtmPxyExtraConfig and gtmPxySpecificExtraConfig configuration
handling:  They were not handled.

2. kill gtm slave handling:  Internal command generation error fixed.

The are intended to be in release 1.1.1 and 1.2.

Further input is welcome.
