dont use repr to quote string in compare_server_default
Fixed issue where server default compare would not work for string defaults
that contained backslashes, due to mis-rendering of these values when
comparing their contents.
The server default comparison still has a lot of not-robust behaviors,
however at least get in place a parameterized test suite so that we
can add new scenarios quickly.
Made a slight adjustment to SQLite's compare server default implementation
to better handle defaults with or without parens around them, from both
the reflected and the local metadata side.
Implemented basic server default comparison for the Oracle backend;
previously, Oracle's formatting of reflected defaults prevented any
matches from occurring.

implement SQLite RENAME TABLE w schema syntax

:meth:`.Operations.rename_table` would render an explicit schema name for
both the old and new table name, which while is the standard ALTER syntax,

a ``Table`` object should be passed to the

reflection may be skipped.

<!-- Provide a general summary of your proposed changes in the Title field above -->
### Description
When working together with `mypy` we have a problem with the default template.
`mypy` raises errors on all migrations when used with https://mypy.readthedocs.io/en/stable/config_file.html#confval-disallow_untyped_defs
So, there are several options:
1. Remove this flag for `[mypy-db.alembic.*]` in `mypy.ini`. This is not a very good idea, because custom code that might get written in this directory might be not fully typed.
2. Edit our own template. This is what we end up doing right now, but this requires some manual work and many users might miss it
3. Update the source! I think that this is harmless (because only python3.6+ is supported), but allows better type-checking
### Checklist
Openning this as a draft for now. Will fix tests after I can see what is failing in the CI.
Issue is also on its way! 🙂
