virsh: Implement command to excercise the bulk stats APIs
Add "domstats" command that excercises both of the new APIs depending if you specify a domain list or not. The output is printed as a key=value list of the returned parameters.

Get statistics for multiple or all domains. Without any argument this
|
||||
command prints all available statistics for all domains.
|
||||
|
||||
The list of domains to gather stats for can be either limited by listing
|
||||
the domains as a space separated list, or by specifying one of the
|
||||
filtering flags I<--list-*>. (The approaches can't be combined.)
|
||||
|
||||
By default some of the returned fields may be converted to more
|
||||
human friendly values by a set of pretty-printers. To suppress this
|
||||
behavior use the I<--raw> flag.
|
||||
|
||||
The individual statistics groups are selectable via specific flags. By
|
||||
default all supported statistics groups are returned. Supported
|
||||
statistics groups flags are: I<--state>.
|
||||
|
||||
Selecting a specific statistics groups doesn't guarantee that the
|
||||
daemon supports the selected group of stats. Flag I<--enforce>
|
||||
forces the command to fail if the daemon doesn't support the
|
||||
selected group.
