Expose admin use in forge implementation

[realaravinth]

Various forges might have different ways to identify a user(username, email ,etc). An interface should be made available to get the admin user's identifier so that hard coding admin user values like we are doing here:

interface/git.py
34:    def __init__(self, forge: Forge, admin_user: str, admin_email):
36:        self.admin = InterfaceAdmin(admin_email, admin_user)

interface/forges/base.py
30:    def __init__(self, host):  # self, base_url: str, admin_user: str, admin_email):

interface/forges/gitea.py
31:    def __init__(self):  # self, base_url: str, admin_user: str, admin_email):
➜  tmp.6358p3u9wv git:(master) rg GITEA.user
interface/forges/gitea.py
211:        path = format("/%s/%s" % CONFIG.GITEA.username, repo)
216:            "git@%s:%s/%s.git" % (self.host.netloc, CONFIG.GITEA.username, repo)

interface/runner.py
97:                if all([n["type"] == PULL, owner == CONFIG.GITEA.username]):

interface/git.py
88:    git = Git(forge, CONFIG.GITEA.username, CONFIG.SYSTEM.admin_email)

Possible Solution:

• interface/forges/base.py:

class Forge:
  def __init__(self, host, admin_user, admin_email):
    self.admin_user = admin_user
    self.admin_email = admin_email
  ...

• Forge implementation(Gitea):

class Gitea(Forge):
   def __init__(self):
       super().__init__(settings.GITEA.host, settings.GITEA.username, settings.SYSTEM.admin_email)
