This MR contains the implementation for #17
The workflow logic is the following:
- A user is created manually on Keycloak
- An OSL Admin logs in and creates an individual with the same username
- The OSL user with role TESTBED_PROVIDER logs in OSL and lands in page individual_update/myuser and enters the geographic location info of the site that manages
- (Optional) If the user wishes can navigate again to the page via edit my profile and can update its information
