xenapi: Use a jeos vm as a template

DevStack was using templating to speed up the setup process with
XenServer. The template already included some devstack customisations,
not just a clean OS. This change modifies devstack behaviour, so that
the template is a simple clean operating system. This makes it easier to
use custom OS as a template, potentially speeding up the tests.

Add call trace in error message

Call trace can help user to locate problem quickly.

stack.sh uses bash as interpreter, which defines a series of
"Shell Variables":
BASH_SOURCE:
An array variable whose members are the source filenames

BASH_LINENO:
An array variable whose members are the line numbers in source
files where each corresponding member of FUNCNAME  was  invoked.

FUNCNAME:
An array variable containing the names of all shell functions
currently in the execution call stack.

run "man bash" and search the variable name to get detailed info.

In function backtrace, it gets the call deepth from
${#BASH_SOURCE[@]}, then print the call stack from top to down.

In function die, backtrace is called with parameter "2" to ignore
the call trace of function "die" and "backtrace".

I add a broken function in lib/database, and call it in stack.sh,
the output looks like this:

[Call Trace]
./stack.sh:104:broken
/home/kui/osd/devstack/lib/database:24:die
[ERROR] ./stack.sh:24 It is broken

misleading source filename in error message

when ./stack.sh encounters error, the output may look like this:
[ERROR] ./stack.sh:698 nova-api did not start

The source filename is wrong. Actually, it should be like this:
[ERROR] /<path_of_devstack>/lib/nova:698 nova-api did not start

stack.sh uses bash as interpreter, which define "Shell Variables"
BASH_SOURCE:
    An array variable whose members are the source filenames where
    the corresponding shell function names  in  the  FUNCNAME  array
    variable  are  defined.   The  shell  function
    ${FUNCNAME[$i]}  is  defined  in  the  file ${BASH_SOURCE[$i]}
    and called from ${BASH_SOURCE[$i+1]}.

The function "err" is called by function "die" ( and "err_if_not_set",
and "err_if_not_set" is not used at all). ${BASH_SOURCE[2]} will
ignore the deepest two call entries, which corresponding to the shell
functions: "err" and "die".

In one sentence, this change will print the source filename where the
function is defined and exits via function "die".

Update baremetal to work with the latest DIB

Adjust DevStack to the current DIB's naming to kernel/ramdisk.

BM_HOST_CURRENT_KERNEL is removed since the kernel is extracted from
a diskimage with the ramdisk and the host's kernel is not used.

BM_BUILD_DEPLOY_RAMDISK is added to control whether use DIB or not.

If you set BM_BUILD_DEPLOY_RAMDISK=False, you must BM_DEPLOY_KERNEL
and BM_DEPLOY_RAMDISK to point existing deploy kernel/ramdisk.

Correctly setup ML2 mechanism_drivers

The ML2 code in devstack was not correctly configuring the mechanism_drivers
when asked to do so. This corrects the typo in the variable assignment, and
also actually sets these in the plugin configuration file.

Add tools/install_pip.sh

Install a known working recent version of pip that handles installation
dependencies more correctly than before.  Extract to a separate script
so it can be used apart from stack.sh.

* Install distro setuptools if it not already present
* Install pip from source tarball as get-pip.py proved to be unreliable
* Remove python-distribute and python-pip from all prereq files,
  move python-setuptools to 'general'
* Remove the earlier unfubar_setuptppls() call that attenpted to fix this
* Only update requirements.txt when no changes in repo

Tested on Precise, F18 and CentOS6.
* Fedora and RHEL allow pip to install packages ON TOP OF RPM-installed
  packages.  THIS IS BROKEN.  And is one reason we have to be so picky
  about order and so forth.
