Removed undefined method in install_env.py file

There was a call from install_venv.py file to post_process method
of InstallVenv class, but this method is not defined in this class
as result it was raising an error. Even when this error doesn't
affect dependencies installation, it is not allowing to display user
information.

Check if the alarm has time constraints field before displaying

Fixes the bug that broke the alarms CLI if the alarm didn't have
a time constraints field.

Reduces code duplication of alarm printing code, so now all the alarm
printing code is actually tested.

Renames some auxiliary methods for more clarity.

Verify alarm found before modifying

Current behavior is to retrieve alarm by id and conduct operations on the
object.  If the tenant doesn't own the alarm or isn't admin, the user will
receive the message: 'NoneType' object has no attribute 'to_dict'

Above message doesn't provide any useful diagnostic information and indicates a
programming error since an unexpected None-type is encountered and not handled.

This change verifies the alarm is found before using the object.  If alarm not
found it prints the same message for a not found Alarm as other PUT operations
like alarm-state-set:  Alarm not found: <alarm_id>.

This message is more useful for diagnosis and gets rid of the uncaught
None-type error.

Fix sample-create in v2 api calls

A dict embedded in a list is the expected input. In
47934c777c50897b649793e0960eebdaad322c45 the list was lost, this
puts it back.

Note that the _exact_ date of this failure was identified by
existing Rally jobs which started failing in early August. That made
searching the commit logs straightforward.

Stop using intersphinx

Remove intersphinx from the docs build as it triggers network calls that
occasionally fail, and we don't really use intersphinx (links other
sphinx documents out on the internet)

This also removes the requirement for internet access during docs build.

This can cause docs jobs to fail if the project errors out on
warnings.

Reduce redundant parameter of some commands in CLI

When deleting an alarm, we use "ceilometer alarm-delete -a <ALARM_ID>",
unlike other deleting commands of openstack, the parameter-a/--alarm_id
is redundant. The similar situations exist in showing alarm, geting alarm
state, showing resource and so on.
It is more easy to use for reducing these parameters.

New behaviour:

$ ceilometer help alarm-show
usage: ceilometer alarm-show [<ALARM_ID>]

Show an alarm.

Positional arguments:
  <ALARM_ID>  ID of the alarm to show.

$ ceilometer alarm-show
alarm_id should not be empty

$ ceilometer alarm-show abcde
Not Found (HTTP 404)

$ ceilometer alarm-show -a abcde
-a is obsolete! See help for more details.
Not Found (HTTP 404)

$ ceilometer alarm-show --alarm_id abcde
--alarm_id is obsolete! See help for more details.
