Deprecate and provide alternatives for logging properties that are
specific to Logback.

The following Spring Boot properties have been changed:

  * logging.pattern.rolling-file-name ->
    logging.logback.rollingpolicy.file-name-pattern

  * logging.file.clean-history-on-start ->
    logging.logback.rollingpolicy.clean-history-on-start

  * logging.file.max-size ->
    logging.logback.rollingpolicy.max-file-size

  * logging.file.total-size-cap ->
    logging.logback.rollingpolicy.total-size-cap

  * logging.file.max-history ->
    logging.logback.rollingpolicy.max-history

As have the system environment properties that they map to:

  * ROLLING_FILE_NAME_PATTERN ->
    LOGBACK_ROLLINGPOLICY_FILE_NAME_PATTERN

  * LOG_FILE_CLEAN_HISTORY_ON_START ->
    LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START

  * LOG_FILE_MAX_SIZE ->
    LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE

  * LOG_FILE_TOTAL_SIZE_CAP ->
    LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP

  * LOG_FILE_MAX_HISTORY ->
    LOGBACK_ROLLINGPOLICY_MAX_HISTORY

This commit also cleans up and simplifies `DefaultLogbackConfiguration`.
