Do not panic when getting metrics and add custom timeout

[labkode]

Fixes #33

This PR adds:

• CollectorOpts for all collectors to pass configuration options (timeout for now)
• New Timeout configuration option to control timing when querying EOS
• Removal of panics to avoid crashing the process and loosing metrics (the error is logged instead, see below)
• make build builds the Go binary with all required build info (from .get_build_info.sh

How to test?
