feat(rust): improvements to portals commands arguments

[adrianbenavides]

• Inlet create commands now have a positional argument to define the portal's name. This argument replaces the current alias or addr. Old arguments are kept as deprecated flags. To ensure backward compatibility, if a deprecated flag is used, it will take precedence over the positional argument
• Outlet create commands also have the positional argument, as an alternative to the --from argument. In this case, we'll keep --from as a valid alternative (not deprecated).
• InfluxDB commands now have their own args definition. This fixes the issue that was showing the TCP commands docs in the InfluxDB commands docs
• The arguments using HostnamePort now use SchemeHostnamePort, allowing the user to optionally specify the scheme (tcp, tls or udp). The --tls and --udp flags have been deprecated (but kept), as this information can now be derived from the address arguments. To ensure backward compatibility, if a deprecated flag is used, it will take precedence over an address with an explicit scheme
• Other args renames (with old names as valid aliases)
• Unhide --allow flag in all the commands

Sorry if my comments are a bit out of order. This is a good step forward but I think that could be even clearer in the naming of "addresses" so that there no ambiguity in the description on what an "address" is. Feel free to open another PR for modification.
