Logging tweaks - moving to formatted logging (from Info to Infof) and adding whitespaces where necessary.

[adam-ah]

• Removing unnecessary newline strings on log commands (\n and \r\n).
• Converting logging from string concatenation (.Info) to formatter logs (.Infof)
• Adding whitespace to crowded log lines

Console example

Logging example to console before

INFO[0000] GoDNS started, entering main loop...
INFO[0000] Creating DNS handler with provider:Cloudflare
INFO[0000] Checking IP for domain domain.com
INFO[0003] Querying records with type:A
 NFO[0003] Record OK: vpn.domain.com - 0.0.0.0

Notice the missing I at INFO on last line and the crowded provider:Cloudflare and type:A log lines.

After

INFO[0000] GoDNS started, entering main loop...
INFO[0000] Creating DNS handler with provider: Cloudflare
INFO[0000] Checking IP for domain domain.com
INFO[0001] Querying records with type: A
INFO[0001] Record OK: vpn.domain.com - 0.0.0.0
