Description:
The instructions (or lack there of) for getting unit tests running fail on Ubuntu 20.04

https://github.com/mysql/mysql-connector-python/blob/master/CONTRIBUTING.rst

How to repeat:
- Fresh Ubuntu 20.04
- sudo apt-get install mysql-server
- git clone https://github.com/mysql/mysql-connector-python.git
- cd mysql-connector-python
- python3 unittest.py

fails with 

2021-04-10 20:53:41,134 [myconnpy_tests:ERROR] Failed initializing MySQL server 'server1': MySQL binaries not found under /usr/local/mysql

You can't use --with-mysql because mysql and mysqld are not located in the same directory.

/usr/bin/mysql
/usr/sbin/mysqld

Creating a symlink to mysqld gets you bit further

- sudo ln -s /usr/sbin/mysqld /usr/bin/mysqld
- python3 unittests.py --debug --with-mysql=/usr/bin

Returns: 2021-04-10 21:04:16,282 [myconnpy_tests:ERROR] Failed initializing MySQL server 'server1': errmsg.sys and mysql_system_tables.sql not found under /usr/bin/share

- python3 unittest.py --debug --with-mysql=/usr/bin --with-mysql-share=/usr/share

Improve documentation or fix unit test build

Thank you for the bug report.

For the latest Debian and Ubuntu versions, you need to use the following paths:

  python unittests.py --with-mysql=/usr -with-mysql-capi=/usr/bin/mysql_config

Please provide feedback if it doesn't work for you.
