[IMP] Add support for module renaming

[sebalix]

Different approach than #64 to move/rename a module to address issue #11:

• new module name is given as an optional parameter: oca-port {source} {target} {addon_path} [--move-to {new_addon_path}]
• store the old name + new name in source/target data object
• move/rename a module once the git history is retrieved (with git-filter-repo, thanks for the tip @trisdoan )
• use git filter-branch to rename the module (see [18.0][MIG] commission + rename to commission_oca commission#610 (comment))
• rename terms in the renamed modules (in PO files, XML-ID references...)
• 🚧 adapt PortAddonPullRequest to work on moved/renamed module (rework patches to apply to target the new module/folder name, ...)

Optional (can be done in a future PR):

• store this info in .oca/oca-port/ directory with Storage class
• read data stored in .oca/oca-port/ so a migration attempt will automatically detect that this module has been renamed in target branch, launching analysis with the right module name

Example

Migrate & rename a module at the same time:

$ oca-port origin/17.0 origin/18.0 stock_packaging_calculator --move-to product_packaging_calculator --dry-run
ℹ️  stock_packaging_calculator can be migrated from 16.0 to 18.0 and moved to product_packaging_calculator

Module already migrated under a different name: ```sh $ oca-port origin/17.0 origin/18.0 stock_packaging_calculator ℹ️ stock_packaging_calculator has been renamed product_packaging_calculator in origin/18.0 product_packaging_calculator already exists on origin/18.0, checking PRs to port... ```
