If they have no current connection would it beneficial to allow the user to pick one? Instead of a warning message.

Also I am unsure the purpose of the host param as the below two scenarios arent covered:

• Scenario 1: if you arent connected it doesnt auto connect to the given host, isntead it just gives a warning it cannot open the file. I think it should ask to auto connect if the given host is on the list. If the host is listed more than once then give me the option to pick which connection to initiate
• Scenario 2: if you are connected to the wrong host, it just prompts to open with the current connection. We should also have the option to switch to the correct connection, again if there is more that one listed conneciton to the same host then allow me to pick which connection to initiate

@julesyan Thanks for your great testing.

1. Yes, we should automatically connect to the host given it is in the list.
2. Right now we don't even have the internal logic to disconnect and reconnect to a new system automatically. Let me see if this is even possible (since we do have APIs to do both separately.)

@julesyan This works now:

@worksofliam I did some testing with this change and noticed a few issues. Refer to my comments below.

Suggested change

	window.showWarningMessage(t(`uriOpen.noConnection`));
	window.showWarningMessage(t(`uriOpen.missingPath`));

Given the example you gave in this PR:

vscode://halcyontechltd.code-for-ibmi/open?path=/home/liama/xyz

I assume this means that the file will be opened based on the active connection. If so, is this else block a mistake because this will not open any file and just give this warning even though I am connected. In the case there is no connection, shouldn't the message be:

window.showWarningMessage(t(`uriOpen.noConnection`));
