Mint tokens rules adaptation

[Mixa84]

What kind of PR is this?:

/kind feature

What this PR does / why we need it:

Restore old behavior for DAT tokens to be able to be minted by owner. When token is added to consortium then allow only foundation and consortium members to mint it, not the owner anymore.
Allowing on regtest everybody to mint any token, except when --regtest-minttoken-simulate-mainnet flag is supplied.

Minting rules after this PR:

 - only mintable by token owner
DAT token not in consortium:
 - token owner
 - foundation
DAT token in consortium:
 - foundation
 - consortium```
