CostManager injection

[artman325]

implement "CostManager functionalty" main goal are make the hook for couple of methods in factory and produced instance to make additional management mechanism

Requirements: factory can:

• setup initial CostManager address
• fill renounceOverrideCostmanager address's list to prevent changing or override CoastManager in instances
• call overrideCostManager(instance, newCostManager) and override cost manager address in certain instance

in Instance:

• shoud be method overrideCostManager for factory owner(or instance deployer if instance was deployed manually) method should execute only if address instance not in renounceOverrideCostmanager list
• need to organize common method or by operation byte in first params or make bytes calldata and parse it in costmanager!!! Summary: to change costmanager address can be changed only by owner factory

suggested methods for injecting Costmanager external calls:

method to inject	params
CommunityFactory:produce( address hook, string memory name, string memory symbol )	address hook, string memory name, string memory symbol
CommunityContract::withdrawRemainingBalance	uin256 balance
CommunityContract::grantRoles( address[] memory accounts, uint8[] memory rolesIndexes )	address[] memory accounts, uint8[] memory rolesIndexes
CommunityContract::revokeRoles( address[] memory accounts, uint8[] memory rolesIndexes )	address[] memory accounts, uint8[] memory rolesIndexes
CommunityContract::createRole( string memory role )	string memory role
CommunityContract::manageRole( uint8 byRole, uint8 ofRole, bool canGrantRole, bool canRevokeRole, uint8 requireRole, uint256 maxAddresses, uint64 duration )	uint8 byRole, uint8 ofRole, bool canGrantRole, bool canRevokeRole, uint8 requireRole, uint256 maxAddresses, uint64 duration
CommunityContract::invitePrepare( bytes memory sSig, bytes memory rSig )	no params
CommunityContract::inviteAccept( string memory p, bytes memory sSig, string memory rp, bytes memory rSig )	address inviter, address invited, uint8[] roles
CommunityContract::setTrustedForwarder( address forwarder )	address forwarder
CommunityContract::setRoleURI( uint8 roleIndex, string memory roleURI )	uint8 roleIndex, string memory roleURI
CommunityContract::setExtraURI( uint8 roleIndex, string memory extraURI )	uint8 roleIndex, string memory extraURI

For all can be called costmanager hook
