Introduce alias to `*SQL` commands and Maven plugin goals

[fbiville]

There are today a number of commands (and Maven plugin goals) that contain SQL in their name... which is a bit unfortunate for non-RDBMS targets.

The list is as follows (based on liquibase.integration.commandline.Main.COMMANDS):

• changelogSyncSQL
• changelogSyncToTagSQL
• executeSQL
• futureRollbackCountSQL
• futureRollbackFromTagSQL
• futureRollbackSQL
• markNextChangeSetRanSQL
• migrateSQL
• rollbackOneChangeSetSQL
• rollbackOneUpdateSQL
• rollbackCountSQL
• rollbackSQL
• rollbackToDateSQL
• updateCountSQL
• updateSQL
• updateToTagSQL
