[Bug] Fix hive-site.xml URI generation

[vt0r]

As usual when dealing with older files, this change contains the actual changes in separate commits from the cleanups.

• First commit makes the change to fix the metastore URI generation logic, prepending the protocol to all hosts in the string as opposed to just the first one in the list.
• Second commit cleans the file to comply with all Rubocop/Foodcritic rules other than line length.
• Third commit came after I realized a similar issue was present in the MySQL loadbalance URI generation logic, which would only append the port number to the last host. Luckily, this issue does not have any real impact, as we're using the default port of 3306. However, should we decide to move to a nonstandard port at any point in the future, we will now be able to replace the ':3306' string with an attribute, and the string will be created properly.
