Prevent overprompting for permission and account

[gjsjohnmurray]

This PR fixes #242

[gjsjohnmurray]

Steps required before merge and release:

• Bump ./types/package.json to 3.8.0
• From ./types run npm publish --tag latest --access public to publish @intersystems-community/intersystems-servermanager
• Update ./package.json devDependencies to use this

[gjsjohnmurray]

@isc-bsaviano please install this VSIX to verify that Server Manager continues working as normal but without the recently-appearing superfluous re-prompting for permission and for account.

That behaviour will continue in the ObjectScript extension and others using our authentication provider until we publish 3.8, they require it, and they tweak their calls (see updated README info).

@gjsjohnmurray I don't use the auth provider in my regular workflows. What's the best workflow to test this?

[gjsjohnmurray]

I assume your intersystems.servers entries contain passwords alongside usernames. Please remove the password from one or more entries, then expand those servers to discover their namespaces. When prompted for a password, type it in and click the key icon on the input title. Then restart VS Code and re-expand those servers. Prior to this PR you would get reprompted to give permission and to confirm which account to use.

Pinging @isc-rsingh in case you are interested in trying this.

Also @isc-tleavitt since you and your team may have been impacted by the recent increase in prompting which this aims to address.

Please note though that the ObjectScript and Language Server extensions will continue to overprompt until this PR is merged and adopted.

@gjsjohnmurray The new VSIX seems fine to me. It works as intended, but since I don't use this on a day-to-day basis I've never experienced the problem that it's trying to solve.
