Mongodb Migrations Laravel Package

• Use mongodb/mongodb instead of doctrine/mongodb (BC Changes)
• Symfony 5 support

• Bug fix: Fixed incorrect usage of the symfony console question helper - sending in a default value as a string https://github.com/doesntmattr/mongodb-migrations/pull/33
• Improvement: Cleaned up some code issues identified by scrutinizer (reduce noise) https://github.com/doesntmattr/mongodb-migrations/pull/37
• Remove unused code: Removed unused abstract migration class attributes https://github.com/doesntmattr/mongodb-migrations/pull/36

The removal of the abstract migration class attributes could be seen as a breaking change except that no one would have been able to use them correctly because they were assigned the wrong thing.

This is the new shiny v2 of the MongoDB Migrations library.

Changes include:

• php7.1 is the minimum supported version
• phpunit 7
• dropped the requirement for "alcaeus/mongo-php-adapter"
• switched to [ ] array syntax
• added Scrutinizer

plus many more updates.

This is a php5.6 release that adds a travis build testing the lowest dependencies.

Version 2.0 development has started from this release.

This tag will be used to continue to support php 5.6. Version 2.0 of this library will require php ^7.1

Only bug fixes will be included in Version 1.* releases.

This is a minor release before we drop support for php5.*
