Doctrine generated SQL unaffected by recipe dbal charset utf8mb4

Currently the yaml configuration in the doctrine recipe assigns the charset value to utf8mb4:

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4

But this does not affect the configuration of doctrine generated SQL as charset and collation of the tables don't inherit this default charset database value.

So SQL generated through doctrine:schema:update --dump-sql keeps adding DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci by table.

This is true even if mysql server is configured to use utf8mb4 by default or ?charset=utf8mb4 is added to DATABASE_URL env variable.

IMHO it would be better to change the defaults for doctrine recipe so generated SQL really uses utf8mb4 by table.

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci

I see that this is related to doctrine/dbal#3003

Hmm, so we could add it now, and remove it later when DBAL 2.7 is out

I'm in favour of merging this.
