[Log] Print INFO log from SDK

[jiasli]

1. Previously in get_logger, logger name is the module name prefixed with CLI_LOGGER_NAME, like cli.azure.cli.core. Now it only takes the module name, like azure.cli.core, to be in sync with the Python SDK's logger name azure.*.

2. Make cli_logger_name customizable, so that all INFO logs under azure.* loggers can be printed, like

   • azure.core.pipeline.policies.http_logging_policy
   • azure.cli.core

3. Previously, logger cli.azure.cli.core's logger name is not printed:

   Modules found from index for 'group': ['azure.cli.command_modules.resource']
   Loading command modules:
   Name                  Load Time    Groups  Commands
   resource                  0.009        35       164
   Total (1)                 0.009        35       164
   

   Now the logger name is printed even for CLI logger when --debug is specified, so that the log source can be better distinguished.

ℹ As before, DEBUG log from both CLI and underlying libs will be printed, so this won't affect DEBUG log.

Example:

> az group show -n fy --debug
DEBUG: knack.log: File logging enabled - writing logs to 'C:\Users\jiasli\.azure\logs'.
DEBUG: knack.cli: Command arguments: ['group', 'show', '-n', 'fy', '--debug']
