CLI - ensure it's scriptable

[Lezek123]

Based on #1571 and #1586

• Allow providing input as flags/args/json where this is not yet implemented (some commands only provide interactive interface)
• Give user the ability to choose between more human-readable output (ie. a table) and output that can be redirected to a file / other commands (ie. raw json, created entity id etc.). Some OCLIF funcionality can probably help facilitate this (ie. --no-color flag can be used to strip any custom colors from the output, cli.table can be converted to csv by passing an additional option etc.)

account:choose was removed in 0334bd3. I assume a merge error or was this intentional?

./cli/bin/run account:choose

Did you mean account:create? [y/n]: n

This was intentional, since from now on the CLI will try to infer the key based on permissions required to send the associated extrinsic and potentially some additional context provided by the user (ie. memberId, workerId etc.). There will be no need to manually choose a specific key before executing a command.

For example:
api.tx.someWorkingGroup.leaveRole extrinsic sent by working-groups:leaveRole command needs to be signed with worker's role key. Based on that and optionally provided workerId (in case multiple worker role keys have been imported) the CLI can infer which key should be used for signing this extrinsic.
