feat: add sessionName in the attach to session dropdown

[huzaifaiftikhar]

Once #1693 is merged users will be able to view the list of running sessions in the attach to session window. It is difficult to filter the sessions via the session-id, therefore, adding the sessionName (if present) to the list of importantCaps.

What's the sessionName?
It seems the value is not a regular Appium stuff.

Yes, it's not an appium capability, this capability is specific to BrowserStack by which we allow the user's to give a meaningful name to their sessions.
Would it possible to accept this PR as a feature request or do you think otherwise?

Could it be possible to build your own custom AD for your platform with this change?

It would be better to define a new module or method to allow a vendor to customize the naming for them.
I don't check around the code well, but something like:

function formatCaps (vendor, caps) {
    if (vendor === 'browserstack') {
        return formatCapsBrowserStack(caps)
    }
    // ...
}

function formatCapsBrowserStack (caps) {
    // do your own logic
}

Or extract the place as a different module.

@KazuCocoa can you re-review? I've created the method formatCapsBrowserstack and other cloud providers can change the formatting as per their choice using a similar approach.
