Use logfmt instead of terminal format

[dmanc]

Why are these changes needed?

Right now our logs look like this:

INFO [01-30|15:23:34.705|github.com/Layr-Labs/eigenda/disperser/dataapi/server.go:514] server running                           addr=:8080 caller=server.go:514

This is because we use "Terminal Format" which should really only be used in development.

Grafana will have an easier time parsing the log if we use logfmt (brandur.org):

We have a use case for terminal log: the nodeplugin used by the operators. May need to check the output there to make sure it's good.

Good point, what do you think about making the format a config flag and make current behavior the default?

LGTM - we should work on using single log framework across repos.
