Pool Roles
Allo.sol exposes two roles for managing pools, a pool manager and a pool admin.
When a pool is created the admin and manager are set to msg.sender.
Pool Admin
The admin can reassign the pool manager using the addPoolManager and
removePoolManager functions.
Pool Manager
The pool manager has the ability to update the pool metadata using the
updatePoolMetadata function.
Additional responsibilities can be granted to the pool manager in the pool
strategy. For example, some strategies may wish to limit access to the
distribute function to pool managers. The BaseStrategy.sol contract
provides an 'onlyPoolManager` modifier that can be used to restrict functions.
