Change the output/stdout when running terracognita also adding VERBOSE mode

[xescugc]

Right now the output it's basically the logs from terrafrom, we should show those when we add the --verbose flag, which does not exists ATM.

The desired output would be, the one without the --verbose, this one:

Jun 19 12:17:01 INFO: Importing security_group [35/35] Done!
Jun 19 12:17:01 INFO: Importing aws_instance [10/35] ...

We still have some things TBD:

• Do we want the TF logs on --verbose? Or we want something custom?
• The TF logs are important? If so where/when do we want them?

EDIT:

We'll have 2 flags -v and -d:

• Without any flag we'll have something like this output

Jun 19 12:17:01 INFO: Importing security_group [35/35] Done!
Jun 19 12:17:01 INFO: Importing aws_instance [10/35] ...

• With -v we'll have the logs we had before with more custom logs (Debug) like this

Jun 19 12:17:01 DEBUG: Starting terracognita for region R - resources: X, Y, Z
Jun 19 12:17:01 INFO: Importing security_group [35/35] Done!

• With -d we'll have the logs we had before with the TF ones:
