change deprecated parameter pw and db

[ziegenberg]

SUMMARY

Parameters db and passwd are deprecated, using database and password is recommended by the DB-API 2.0.

This MySQL collections support two connectors:

• PyMySQL
• MySQLdb aka mysqlclient

In PyMySQL the change from the short parameter to the new long-form was made with v0.6.7 (and the short forms are kept as an alias for database and password). Warnings will be activated around 2022 (for details, see PyMySQL/PyMySQL#939).

In MySQLdb the change was introduced with v1.3.8 (and the short forms are kept as an alias for database and password).

@ziegenberg thanks for working on this!

@Jorge-Rodriguez as I remember you implemented very good checks for mysql versions. Maybe you have ideas on implementation?

[Jorge-Rodriguez]

@Andersson007 sure, I can get on that but I'm in the middle of moving, so I can't handle it straight away. I'll give it some thought in the meanwhile

[Jorge-Rodriguez]

LGTM

[Andersson007]

@Jorge-Rodriguez sure, thanks!
@ziegenberg we should make the CI tests green. After that, we can ask our WG leader to review the PR, thanks!
Exception message: module 'MySQLdb' has no attribute '__version__'"

[ziegenberg]

I can have a look at it on the weekend

[Andersson007]

@ziegenberg perfect (no rush)!

[Jorge-Rodriguez]

These changes are dependent on #141

[Andersson007]

Any updates on the PR? If it's irrelevant, please close it

[Jorge-Rodriguez]

The old versions of the database plugins are no longer supported on the collection. So I have removed the conditional checks, leaving only the currently supported parameter names, unconditionally.

@ziegenberg @Jorge-Rodriguez thanks for the contribution!
