Increased logging to console and introduced file logging to facilitat…

…e troubleshooting.

File logging:

-uses pino and pino-pretty logging libraries
-log level is controlled via the --log-verbose option which will output more information to the file (default log level is INFO)
-queries and node/edge data are logged at DEBUG level and not logged by default

Console output:

-added more messages and spinners to indicate what the utility is doing and its progress
-yellow text is used to highlight some information for the user

Other:

-fixed sample TODO schema which had extra data that causes it to fail when used as an import schema
-deleted unused test case input graphql schema files
