Examples

canonical_data_syncer --verbosity

canonical_data_syncer --default

canonical_data_syncer -e

Current behaviour

The program silently ignores the missing value and performs the "sync" behaviour with the default options.

Expected behaviour

We should show an error like

Error: '--verbosity' was given without a value

Error: '--default' was given without a value

Error: '-e' was given without a value

And show the help message.

Fix(cli): Show error message for missing value
dffd5cb 
For example, the command:
  `canonical_data_syncer --verbosity`

Now produces:
  Error: '--verbosity' was given without a value

And shows the help message.

Previously, the program silently ignored the missing value.
