Collector "No * configured" warnings mislead users

[Steve Baker]

Users who are debugging unrelated issues are frequently interpreting the following as an indication that os-collect-config is misconfigured when the warning is actually harmless:

WARNING os_collect_config.heat [-] No auth_url configured.
WARNING os_collect_config.request [-] No metadata_url configured.
WARNING os-collect-config [-] Source [request] Unavailable.
WARNING os_collect_config.local [-] /var/lib/os-collect-config/local-data not found. Skipping
WARNING os_collect_config.local [-] No local metadata found (['/var/lib/os-collect-config/local-data'])

A better experience would be to log as INFO and log something regardless of whether the collector is configured or not.

    Log with info instead of warn when collector not configured

    Users who are debugging unrelated issues are frequently interpreting
    logged warnings as an indication that os-collect-config is misconfigured
    when the warning is actually harmless.

    This change uses info instead of warn for this logging.
