Changed what sequence attributes are included in diff/generate changelog for Snowflake

[yodzhubeiskyi]

Impact

• Bug fix (non-breaking change which fixes expected existing functionality)
• Enhancement/New feature (adds functionality without impacting existing logic)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

Snowflake only supports operating 'startWith' and 'incrementBy' sequence attributes. The rests are set by default and are not allowed to be set or changed. In order for Liquibase to correctly work with those 'fixed' attributes we need to:

• Throw a validation error when the 'fixed' attributes are present in changesets that are being applied to Snowflake
• Include the values in JSON snapshots so the database is accurately and completely represented BUT
• Exclude the 'fixed' attributes from any changesets generated by diffChangelog or generateChangelog so that we don't generate invalid changesets
