Fix for user custom attribute issues

[AndyDLP]

Description

This PR fixes the issues I reported in #158, where defining custom_attributes that included a hypen - in the name such as msDS-SupportedEncryptionTypes threw errors due to incorrect quoting of hashtable keys.

It also fixes an (unreported?) bug where if a custom_attribute was a large number (e.g. uidNumber = 7333677) it ended up being formatted with an exponent which then threw an error.

Tested successfully on Windows 10 & Alpine with terraform 1.2.7 & 1.4.2
