assign variables to build object in 10_setupvars.rake

This commit updates 10_setupvars.rake to create a BuildInstance object and
assign our various settings to it, rather than global instance variables. We
defeated encapsulation at the origin of the packaging repo, but here it makes a
defiant return. This commit also modifies variable loading to load everything
from a yaml file we pass in the path to with the PARAMS_FILE environment
variable. This takes advantage of the BuildInstance ability to read in
attributes from a yaml file and write them back out again. We also don't need
explicit parameter setting any more for the most part, since the build object
will read in for us, but we keep the ability to override some parameters with
environment variables.

1 to 1 mapping in params and variable names

Why I ever decided to name the instance variables something other than
their respective yaml file entries is beyond me. This commit fixes this
by replacing all instances of @name with @project, which is what it is
in the project_data.yaml file.
Update 20_setupextrasvars.rake for Build object

This commit updates the loading of extras vars in lieu of the new build
object architecture. This allows us to read in data from the extras
files as needed without worrying if specific parameters are defined or
not. The currently 'overrideable' params are still kept as such to make
sure we can still override as necessary.

Replace instance vars with build.<attr>

This commit replaces instance variable evaluations throughout the tasks
with accessor calls to the build object.
Remove environment variable passing to remote tasks

This commit adds a utility method to send the build parameters to a
remote host and return the path on the remote filesystem as a string.
This method is then used in the remote tasks to determine various
parameters required for the build. This gets us out of the business of
passing along environment variables to the remote tasks, a source of
much pain as the remote tasks have become more complex.

Add DEBUG printing of all variables

This commit adds a debug parameter to the build object that we use initially to
print out all variables if passed. This can be used later as a flag for other
such behaviors as we chose.
Set instance variables for backwards compatibility
Make @name = @project for backwards compatibility

This commit also adds some more comments to 10_setupvars.rake, and tries to
standardize some formatting around comments.
Enable output dir for params write, add tasks to wrap

This commit adds tasks for printing and writing all build parameters. This
enables us to leverage this file for great purposes, such as passing into a
queuing system for builds. Printing is nice for debug.

Remove unused variables in pe sles build

We moved this data into the build-data, which means we no longer need it
defined here. We're not using it and it has no value.
