Add server<->server sharing

Do not rename primary key index when renaming table

Obviously have to pass the hostname as is when there is no ':' in the hostname

Migrate table layout to p layout for share settings

Added unit test to make sure that checkMigrate() works when adding a
primary key and autoincrement column to a table schema.

When the migrator renames a table, for example for upgrade simulation,
it should not rename the primary key to avoid messing up with the diff
because the MySQL Doctrine code expects that index to always be called
"primary".

This reverts commit 73062040.
