* Adds an option to disable features based on token data.

Reverts changes from b84e910086, removes disableDesktopSharing option and an interface_config option.

* Disable recording button based on token features data.

Hide recording if local participant isGuest and roles based on token.
When enableUserRolesBasedOnToken is enabled we were not hiding the record button for guests.

* Adds filtering of jibri iqs and rayo based on features.

Moves feature checking in separate utility function.
Renames utility method.

* Adds a footer text when outbound-call is not feature enabled.

* Fixes comments.

* added checks for audience and issuer values
default audience and issuer checks to validate only appId
added missing documentation lines from the previous PR for context_user and context_group session values

* support for accepting any audience
option set to accept any audience by default

stick user and group from token context into session if available

Allows '*' in jwt to allow connecting to any room.

Room name verification crashes when we have a configured anonymousdomain as it doesn't have any token extracted data. It is safe to skip this check as room creation is verified by jicofo and we have the option restrict_room_creation to admin users.
Removes obsolete print when updating jitsi-meet-tokens.

Adds option to enable/disable domain checking, disabled by default. Domain verification for multiple domains depends on new option muc_mapper_domain_base.

This option is useless, as if we do not need to verify room name, we just disable the mod_token_verification module.
