fix: url quote passwords

[LyndonFan]

Changes

Updated DbContainer to fix #547 by using urllib.parse.quote. I referenced sqlalchemy's implementation, but have not imported the library.

I have chosen to make this behaviour occur at all times (can't opt in / out), as it is common, if not the standard for these urls.

Tests

Since DbContainer can't be tested on its own, I put the tests across various database containers. I have pasted the below as comment in the test files for the listed modules:

# This is a feature in the generic DbContainer class
# but it can't be tested on its own
# so is tested in various database modules:
# - mysql / mariadb
# - postgresql
# - sqlserver
# - mongodb

Note the discussion recommended me to test with oracle, but I was unable to spin the container up locally (even with colima), so opted to replace it with mongodb.

Is there a template for PRs for the core library? I am unable to find one so have opted the above format. Please let me know if I have missed anything in this PR. Thanks!

looks good, running these tests on my machine first and fixing some stuff up with static ports

had this other thought: do we care to simulate the craziest input possible, or is it better to replicate exactly the situation you saw, which is the auth denied error? not sure, maybe you have considered this though

e.g.

diff --git a/modules/mysql/tests/test_mysql.py b/modules/mysql/tests/test_mysql.py
index 62deac5..8ab347f 100644
--- a/modules/mysql/tests/test_mysql.py

maybe the answer is to parametrize, or i am just overthinking it

opened #550 because debugging mssql is very not fun on a mac at the moment.
