- #314: dry-run option

To know that an uid and a pubkey can be passed as argument
It is not possible to add an help on argument() as for option()
https://click.palletsprojects.com/en/7.x/arguments/

to choose identity among identities from wot/lookup
Display the uid, pubkey and the blockstamp to choose
Add tests on choose_identity()

Delete get_information_for_identity() based on top of the lookup

Allow to pass pubkey to the following commands:
The uid was the only identifier before
Adapt 'wot' and 'cert' commands to choose_identity()

Import silkaj.wot and click directly
Import directly bma otherwise there is a namespace conflict on 'wot'
on silkaj.wot and bma.wot

Harmonize by calling top-level click cmds group in CliRunner.invoke(cli.cli)
Merge the command in the same line
Directly monkeypatch the imported 'bma' module

- Clean unused imports

Passed pubkeys with a checksum wasn't returned without the checksum

recipient/outputAddresses: Click stores the arguments in a tuple which
is immutable. Convert it to a list in order to be able to change it.
Though it is not necessary to return the value since it's a list.

outputAddresses: use enumerate in order to assign the pubkeys without the
checksum

ouputBackChange: remove duplicate call to check_public_key()
store pubkey in case it get erased by a boolean
Return the value as a string is not a pointer and does not get modified
in the parent scope as a list or a dict.

Add comments in check_transaction_values()

Add a comment about default port if not specified
Use defaults endpoints from constants

To represent what they contain:
- value -> inputs_balance
- amount -> balance

Which is hardly comparable the more N is bigger
The comparison to M/N makes more sense
We could round to five instead of two digits, to be able to see
something, but that does not make sense as explain earlier

- To avoid 503 http code error got when reaching the request spam limit

- Will be removed from GitLab v13.0
- https://docs.gitlab.com/ee/ci/yaml/#rules

Too much requests at the same time to determine the corresponding uid was rejected by BMA

- time.sleep() has no effect on asynchrone requests

* create a patched get_sources() function

    * use display_amount() to display pubkey's amounts

* modify test_transaction_confirmation() to match new behavior
    * add new test case
    * remove useless float()
