CLOUDSTACK-9914: Update Quota plugin to support currency values up to 5 decimal places (#2123)

Summary: this commit alters column currency_value from table
cloud_usage.quota_tariff to support values up to 5 decimal places. The
current implementation allows up to 2 decimal places.

Issue: need to use more than 2 decimal places to define resources values
in Quota tariff.

Solution: modify column currency_value from table
cloud_usage.quota_tariff to support values up to 5 decimal places.
Values with more than 5 decimal places will be displayed with scientific
notation in the user interface.

SQL command: "ALTER TABLE cloud_usage.quota_tariff MODIFY currency_value
DECIMAL(15,5) not null"
