As PluginMgr class contains only one method it's
better to move it to pluginbase to have all plugin
related APIs in one module.

Call methods directly instead of getting them with
get_plugin_methods and then calling.

Simplified the implementation of get_plugin_methods:
- get rid of looping over the dicrtionary, used access by key instead
- get rid of filling a dictionary that passed as a parameter

Instead of making a singleton object of PluginMgr class
it's simpler to use PluginMgr class directly as any class
is a singleton.

Replaced msger with wic logger in the core wic modules.

It will omit the given path from the resulting partition, and if the
given path ends in a slash, it will only delete the content, and keep
the directory.

Since mkfs only accepts whole directories as input, we need to copy
the rootfs directory to the workdir so that we can selectively delete
files from it.

Since we want to use the copyhardlinktree() function, we need to put
the generic oe lib in the module search path.

Added new option --fixed-size to wks. The option can be used to indicate
the exact size of a partition. The option cannot be added together with
--size, in which case an error will be raised. Other options that
influence automatic partition size (--extra-space, --overhead-factor),
if specifiec along with --fixed-size, will raise an error.

If it partition data is larger than the amount of space specified with
--fixed-size option wic will raise an error.
