Do we need both ProjectName() and ProjectID()?

Removed this, not needed for now

I suspect that this roundrip of converting the config file back to a gce.conf may not work.
To elaborate, I think json.Marshal(), when converting the structs to JSON would use the default camelCase names for the fields. So something like NetworkProjectID ends up in JSON as networkProjectID.
On the other hand, when gcfg code reads the json, it is likely using the gcfg struct tags to interpret the field names. So it expects the JSON field name to be network-project-id.

Good catch
I changed the code significantly. Now it treats the file as ini file, and, I also updated unit tests to double check it, looks correct

I'm contemplating whether it's helpful to refactor some of the code here that's shared with the NewGCEClient within glbc/app package. On one hand I feel it's maybe not that complex that it needs de-duplication, but on the other hand it maybe feels more natural to just have it in one place (perhaps within the glbc/app package?). Any thoughts?

I moved a part of it into glbc/app, so we reuse some code, and it just makes it clearer :)
- Still uses default gce.conf to get most of the info - If project info not specified will use default config values, which corresponds to cluster-project - Overrides TokenURL and TokenBody and Network info if project is specified - Imports new package github.com/go-ini/ini to properly work with gce.conf which is in ini file format
