Client Changes for Guest Log File Retrieval

Implements log file retrieval from the guest agent.  The contents
of the log file are pushed up to a swift container as a series of
objects that represent a subset of the lines in the log.

The following trove CLI commands are implemented:

trove log-list <instance>         : lists log files available on guest
trove log-enable <instance> <log> : enables writing to log file
trove log-disable <instance> <log>: disables writing to log file
trove log-publish <instance> <log>: publishes updates to swift container
trove log-discard <instance> <log>: discards published logs
trove log-tail <instance> <log>   : displays last lines of log
trove log-save <instance> <log>   : saves the entire log to a file
