Merge branch 'jwt' into 'master'

Removed format validation

**What does this MR do?**

Removals format validation for drone token

**Are there points in the code the reviewer needs to double check?**

Nothing

**Why was this MR needed?**

because drone migrated to JWT tokens and JWT token doesn't valid with current format ( i don't know how many symbols JWT can use for this )

See merge request !1359
