Panic on errors

[pkaeding]

It seems that there are many places in connector.go (and maybe elsewhere in the code) that panic when an error is encountered, instead of returning an error (which is more idiomatic in go). This means that our application is unable to gracefully deal with errors and recover/retry.

Thanks will work on eliminating the panics.
