Update wmcore_transferor global and local quotas dynamically

[haozturk]

Currently, wmcore_transferor quotas are statically set and it's as follows [1]. Its usage reached to record high of 44.4 PB [2] and made many sites run out of space. In this issue [3], we discussed a strategy to introduce global and local limits for this account to keep its usage under control. This PR implements what's been discussed in that issue as well as my additions. To explain the changes:

1. Implements a global limit for this account over the T1 and T2 RSEs. The global limit is set to X % of total disk capacity of T1 and T2 sites used in production. The default is 15%, which correspond to ~46 PB. Beyond this usage, rule creations will fail. This is to keep its global usage under control.
2. Implements a local limit at every T1 and T2. This is to avoid the over-usage at individual sites. Its local quota is set to Y % of an RSE's (free + expired) space. The default is 70%.
3. Creates a new helper file to store commonly used functions for their re-use.

The output of a dry-run can be found at [4]

Before Eric reviews it, I'd like to get Ops' and WM's feedback. That's why I'll mark the PR as draft for now. Once we agree that the PR reflects what we need, I'll open the PR for Eric's review. Let me tag @Panos512 @hassan11196 @drkovalskyi @amaltaro @eachristgr and @juanpablosalas
