Add new log tab table to instance details to display the list of logs that can be retrieved. The table has row options to view the log in a separate panel, publish new log data and stop collection of log data. The log data is displayed in a new panel. In this panel the number of lines to display can be changed. Also checking the publish checkbox and refreshing the log data will publish any new log data. There are three buttons that perform the following actions: * view the entire log in a separate window * download the entire log * return to the log list panel The log code is placed in a subdirectory of database to keep the code more manageable. Added the supporting log commands to the api. Change-Id: I577bcb598932d4a4568e22176671f1b67aceb787 Closes-Bug: #1548514
