Support for multiple matrix accounts

This is interesting for me because we have a company HS which we want to use for channels private to company business and I also want to be logged into channels in a personal context (so if I get fired I can stay in these channels). A colleague of mine has suggested that if we adopt matrix he might keep multiple full riot.im instances because this feature is missing.

showerthoughts: if we have multiple account support, what are security implications? for example, if one HS is in internal network without federation and second HS is federated (ergo public) and both meet in one (web) client, can motivated attacker gain somekind of access to internal HS with xss from public HS? is #1977 related? seems like that security risks are similar when, for example, use same irc client for internal and external networks.

Supporting multiple HSs from a single app is a good feature though so it should not be blocked because of security concerns which can (should) also be mitigated by CSP (see #3632).

for the web-version I can workaround with hosting the web-client under multiple domain-names. but for the iOS/desktop version that is not possible, although it should technically be easy to simulate the "multiple-domain-names" behavior.

Desktop version it is possible by starting it with --profile=newProfile1 replacing newProfile1 for each new profile.

For Android app we can use App Cloner app to clone Riot application and sign in to different account in copy. In my phone now works normally 3 Riot copies together with different Matrix accounts. Maybe iOS have same feature.

As example for Electron app - we can see http://rambox.pro/ project that have separate tabs for different messaging apps, also it provide to run multiple Riot instances.

I imagine peoples will have multiple account like they do with email (one for job, university, personal, secret ..). Having a HS is a trade off without multiple sign in. I don't want to use my account on the university HS to chat with my mum... I also want to be able to disconnect from my job account when I'm in vacation!
