change the defaults for ignore_xxx_erros

[dpmramesh]

gdeploy has a config to ignore the erros. we have to specify 'ignore_xxx_erros=yes' if you want to ignore erros and 'ignore_xxx_erros=no' if you don't want to ignore errors. Here default is 'ignore_xxx_erros=yes', which means gdeploy will ignore all the errors by default unless we specify 'ignore_xxx_erros=no' in each section. I feel this is confusing. It is better not to ignore errors by default, and when user wants to ignore errors we can expect him to specify 'ignore_xxx_erros=yes'. Currently I am adding 'ignore_xxx_erros=no' to all the sections.
