Log improvements

[Aergonus]

The commits contain detailed info which I'll copy below.

tl;dr

• Standardized log levels
• Added descriptive prepend to logs
• Added ability to fmt.Println(schedule)
• Added descriptive Logging glog style for schedule

---

Log status and schedule per line

Converted some logs to their appropriate type (i.e. error to info or vice versa)
Reworked schedule print
Standardized glog levels grep -r V\([0-9]\) *
L0: None
L1: Highest Level current status info and Errors with Terminations
L2: Successful terminations
L3: More detailed schedule status info
L4: Debugging verbose schedule and config info
L5: Auto-resolved inconsequential issues

Schedule String()

Allows for fmt.Println(schedule)

Switch Print() and String()

Since we should glog the single line info
and make the table version isolated and readable

I would omit this in the final version since it's really intended for someone debugging and expects that this should work
